Generate Post Thumbnails

UPDATE: Now supports externally hosted images.

UPDATE2: Externally hosted images generation was improved.

WordPress 2.9 introduced the new feature Post Thumbnails. This feature allows to assign post thumbnail at post Edit page for each post, specify post thumbnails sizes in theme settings, and easily call post thumbnail of specified size in any place of the theme. Read more information about this feature at Mark on WordPress – New in WordPress 2.9: Post Thumbnail Images

The plugin Generate Post Thumbnails helps to automatically create post thumbnails for existing posts using post images. This plugin by default takes the first image in the post content and assigns it as a post thumbnail according to specified settings in the theme.

Plugin management page

I found this helpful after I decided to use Post Thubmnails feature in existing WordPress blog. I upgraded my WordPress to 2.9 and altered my theme settings according to New in WordPress 2.9: Post Thumbnail Images. I had hundreds of posts already, so I needed an automated script to run through them and assign my first post image as a post thumbnail. This is when this plugin came in handy. It is working using Ajax requests, so there is no timeouts issues. For my 200 posts it has been executing for 4 minutes. Anyway, this is faster than to do this process manually.

Requirements:

Installation

  • Download plugin
  • Extract zip in the /wp-content/plugins/ directory.
  • Activate the plugin through the ‘Plugins’ menu in WordPress.
  • Open the plugin management page, which is located under Tools -> Generate Thumbnails. If you get plugin warning, that means either your theme does not support WordPress Post Thumbnails feature or your WordPress version is lower than 2.9. See related links for more information.
  • Set Overwrite parameter, if you want existing post thumbnails to be overwritten by generated thumbnails.
  • Set the number of the post image, that you want to be used as your post thumbnail.
  • Click on Generate Thumbnails and wait until process is finished.
  • After this plugin assign all post thumbnails I suggest to use Regenerate Thumbnails plugin if you changed your media settings or theme post thumbnails settings and need to regenerate new thumbnails.

More useful plugins:

  • Regenerate Thumbnails - recreates already existing post thumbnails after changing their settings; however, it does not assign them if the post has no thumbnails yet.
  • Auto Post Thumbnail – generates post thumbnail after post saving.

    • http://lisaclarke.net Lisa Clarke

      This is *exactly* what I’ve been looking for, with one notable exception – most of my post images are hosted on Flickr. Any chance there will be a version of this plugin that will support external images in the near future? Thanks!

    • admin

      Lisa, thank you for your feedback. Currently there are no plans to support external images in the near future, but I’ll consider this.

    • Jack

      Is there a way to access the function that generates the thumbnail to auto create a thumbnail for a post when it saves?

      Thanks again for this wonderful plugin!

    • Jack

      Read up a little bit on the subject. I think that if you call your function process_images() using $postid for the $post_id and then register it with

      `add_action( ‘save_post’, ‘process_images’ );`

      or something along those lines it could work…

    • Jack

      I hope these comments aren’t driving you crazy. I added this to the bottom of the plugin:

      `function GeneratePostThumbnailsOnSave() {
      global $GenearetPostThumbnails;
      $GeneratePostThumbnails = new GeneratePostThumbnails();
      $GeneratePostThumbnails->process_images();
      }

      add_action( ‘save_post’, ‘GeneratePostThumbnailsOnSave’ );
      `

      And now it works great.

      Thanks for your wonderful plugin!

    • admin

      Hi Jack, that’s a cool idea to add such a functionality to the plugin. You can also add the following code to the plugin on line 26.
      add_action( ‘save_post’, array( $this, ‘process_images’ ) );
      I’ll add it to the next release, thanks!

    • Jack

      Thanks! much simpler! =)

    • bobby

      so, there is no support for external link image…
      ehm.. is there any other plugin like post thumb but it supports external link image like from flickr or picasa image host ?

      Thanks for adding in the auto-generate feature for 0.5!

    • admin

      Hi Jack, this feature is commented on line 27 of new plugin version. As I found plugin that does exactly the auto generation of thumbnails http://wordpress.org/extend/plugins/auto-post-thumbnail/
      So I decided to keep my plugin as WordPress tool not a setting.

    • Joris

      I tried to generate thumbnails for all the posts, unfortunately it didn’t do anything. Everything looked fine; the process was finished…

      Any known issues?

    • admin

      Hi Joris, there could be a problem with relative image sources in last release. This will be fixed in the next one.

    • Joris

      That will probably be the case, since I tested it on a mirror site. Any idea when the next update will be? Thanks.

    • admin

      Joris, should be next week

    • Joris

      Do you know how I can generate thumbnails from a post gallery image? Since it is only possible to generate thumbnails from the post body with your plugin?

    • admin

      Joris, I don’t know if there is any plugin that does that.

      My plugin actually gets image from post body, than it checks if it is hosted on server. If it was uploaded via WordPress than it gets that image attachment that is stored in WordPress gallery and assigns it as post thumbnail.

    • Cynthia

      This is exactly what I was looking for. Great plugin, however it keeps freezing. I am using WP 3.0 – I have approx 300 posts, so I understand it may take a while, but I can’t get more than 48% and it has been running for an hour. Please help

    • admin

      Hi Cynthia, thanks!
      Is it possible to detect which post causes such freeze? This plugin should process posts in order by their creation date.
      Do you use externally hosted images?

    • http://www.make-it-do.com Calli

      Hi Maria, your plugin is just what I was looking for. I am in the process of moving my blog from wordpress.com to a self hosted wordpress blog. I am leaving the images from my old posts hosted on the wordpress.com server. I installed and ran the program. It showed that it ran the 300+ posts that I have, but only 80 thumbnails were generated. I am running wp 3.0. Do you have any ideas about what might be going wrong? thanks, Calli

    • admin

      Hi Calli, the possible problem may be that connection to externally hosted image was too slow, and plugin was not able to upload it for the given timeout. This plugin gives 10 secs wait time for each externally hosted image, if there is no result it just skips this image. You can try to run plugin again without overwrite parameter (so it will skip already generated images).

      Also, please check, that you have enough space on your hosting server to upload the rest pictures.

    • http://make-it-do.com Calli

      Thanks for your reply Maria. I noticed that the script did run correctly as I did have 300 plus images in my upload folder on the server. They were sized correctly 150 x 150. However, the script seems to have appended the extension in the majority of images. So of the 300+ that I ran maybe 80 showed up. The ones that didn’t had a format like photoname.jpgXXXXXX1234 It appears that the script added a variables after the .jpg extension and those were the images that didn’t show up on the site. Does that help?

    • admin

      Calli, I was able to reproduce this issue. I just updated plugin http://wordpress.org/extend/plugins/generate-post-thumbnails/ to the new version 0.7, where I fixed this problem.

      You can run this plugin again with Overwrite parameter OFF, and it will generate thumbnails for incorrect image names, as they were only uploaded on server and not further processed as wrong formatted, i.e. they were not linked to your posts as thumbnails in WordPress.

      Thank you for your help in detecting this problem.

    • Mehmet

      Hi Maria,

      I need your input on that. Any help is greatly appreciated.

      For some reason plugin does not want to generate post thumbnail for some posts. Have you faced with suc situation? I mean i have over 400 posts, when i run it it just skips over 200 posts without thumbnail while images are actually in media gallery of the post.

    • http://make-it-do.com Calli

      Hi Maria, thanks for the update. This seemed to work a lot better and did get most of the images for my posts. One additional question… For each image the script generated four .jpgs in four different sizes. The fourth being the 150 x 150. Is that correct? I was thinking it would just generate the thumbnail.

      Thanks,

      Calli

    • admin

      Hi Calli, this is correct. WordPress generates 3 additional images for each uploaded image, according to “Media” settings.

    • admin

      Hi Mehmet, please check that you updated this plugin to its latest version 0.7 (just released yesterday). You might probably have the same problem as Calli.

    • http://www.team-decade.com Gaspard

      Great plugin

      Feature request:
      Will that be possible to specify a custom field where the plug in sould look first! and then add this picture as thumbnail

      Lot of people/Theme as been using Post thumbnail stored in custom field
      this would help use to copy the image we selected before in the post thumbnail

      or maybe anyone knows a plugin that does it already

      thanks for your help

    • admin

      Gaspard,
      ops sorry I thought this comment was to other plugin.

      Right now you can only generate thumbnail from the first post image. I agree that this is useful feature, and I’ll try to add this in future release. Thanks for your feedback!

    • http://www.team-decade.com Gaspard

      Thanks a lot!

    • Katja

      When I click on Generate Thumbnails it stops at 40% each time… What am I donig wrong??
      Please help!

    • admin

      Hi Katja, please check that you have enough space on your server for the rest images.

      Also, if you can find on what post it stops it could help me to check it. They should be processed in date order.

    • http://missnymo.com/creative missnymo

      Hi, and thanks for a great plugin! It works fine except one thing; it only generates thumbnails for some of my posts. There are many thumbs missing after generating. I moved my blog a couple of months ago from blogger, so a lot of the images are still hosted there. But there are images from both blogger and my new wordpress server that are missing… Do you have any idea how to fix this? My blog: http://missnymo.com/creative

      Thanks!

    • admin

      Hi missnymo, I was able to look at your blog only now, it seems like many of your posts have thumbs now. Did you set the rest thumbs manually? Sometimes there are could be some timeout issues if images are hosted externally.

    • http://missnymo.com/creative missnymo

      Hi, yes I did it manually. Had to change other things in many of my posts anyway. Another issue I find is when I click on one of the posts, the “featured image” is displayed where the header is suppose to be. I’m using firefox on a mac. Is it suppose to be like that? I’ve never used featured images before so not sure how they work…

    • Shawn

      Great plugin :)

      I’ve got’a second the feature request by Gaspard to have the plugin check for a custom field before looking up and adding the first image in the post… I’ve had no luck in finding a plugin / function that will turn an image into the post thumbnail when that image is not in the post body. If a new feature would let you specify different methods of sourcing of the image, like by custom field / post name / post id instead of only by image position in the post, that would be hugely useful! It would be the only plugin that offers that option as far as I know

      Personally I want to use an image for a thumbnail that’s main use will be in gallery page display so the image will not appear in my post at all, a plugin looking in the post body won’t find it. I do not want to have to use the tedious dialogs in wordpress to upload or set my post thumbnails, I’d rather just ftp my images to a specific folder and have them set as the post image automatically based on how the image filename related to a custom field value or [better yet] the post name.

    • admin

      Hi Shawn, I see. I am going to add Custom Field support probably in the next version.

    • http://uncorneredmarket.com/ Daniel Noll

      @Shawn: I’ll second the request to search first for a custom field. Would be very useful.

      Terrific plugin, in any case.

    • admin

      Hi dgrut, this plugin is working as a tool, and it generates thumbnails once you run it. If you want to automatically generate thumbnail once the post is created, I suggest to use this nice plugin Auto Post Thumbnail – http://wordpress.org/extend/plugins/auto-post-thumbnail/

    • ntlk

      Thanks for the plugin! Very useful.

    • http://www.li-an.fr/wpplugins/ Li-An

      I was testing all the other plugins for this (they were stopping their work, stupid plugin) et yours saved my life ! Thanks !!

    • admin

      Thanks, Li-An and ntlk! I am glad it saved your time as well!

    • http://www.li-an.fr/wpplugins/ Li-An

      Oh no ! It did not work as expected. I do not want to show the images in the post but in a different view so the image is attached to the post, chosen as featured image but as it is not insert in the post, your plugin delete the image !

    • admin

      Li-An, yes, this plugin takes the first image in the post body for “Featured Image” (locally hosted or external does not matter). If there is no image in the post and “Overwrirte” parameter is turned “On” it will remove “Featured Image”. I wrote this in FAQ http://wordpress.org/extend/plugins/generate-post-thumbnails/faq/
      Sorry this doesn’t work as you expected.

    • http://www.li-an.fr/wpplugins/ Li-An

      Too bad because the plugin seems to be the faster and more efficient plugin of this type. Wonder why you choose this as thumbnails maybe not chosen by the user to be inserted as image in the post… :-)

    • http://www.li-an.fr/wpplugins/ Li-An

      Sorry, after reading a new time your description, I understand I did not correctly understand the use of the plugin ! You can delete all my dumb comments here…

      Suresh Khanal, thank you, these two plugins complement each other.

    • http://www.kizmi.com Lisa Zhou

      Thanks for the plugin! But I have one problem… It stops at 76% everytime. I tried it with and without overwrite mode. can u figure out what’s wrong?

    • admin

      Hi Lisa, I just have some ideas, like if your images are externally hosted may be there is a problem in connecting to one of them or there is not enough space on your hosting server. Are they hosted externally and how many posts do you have?

      I heard about this issue, and I tried different approaches, but I couldn’t reproduce this problem.

    • http://moldnews.eu serhio

      Hate this plugin… It “removed” all my images from the blog…. replacing them by pictures of 0 Kb size… I was shocked.

      Thank you very much for killing all my pictures… bull sh…

    • admin

      Hi serhio, I am sorry this happened to you. But this plugin does not touch your blog images. The only thing it changes is “Featured Image” block for each post. It does not remove images from your blog server and it never changes blog post body. If you don’t like the behavior of this plugin, you can always set “Featured Image” back again yourself.

      Please read more about “Featured Image” here: http://markjaquith.wordpress.com/2009/12/23/new-in-wordpress-2-9-post-thumbnail-images/

    • http://moldnews.eu serhio

      in fact, what happened….

      My old images were not deleted. Just all my posts lost their images in a way…

      I have a lot of pictures in the gallery with the same name, 0 kb, a “picture” for each post….

      The old pictures is still in the gallery, but not used anymore.. so I need to delete all 0kb picures, and reset the post with old pictures from the gallery…

      But this is crazy… hounded of posts, for each generated a empty picture… now to delete all this pictures is not enough to delete it with ftp, but there is need to delete each of them from the gallery…

    • admin

      Serhio, so this plugin created 0Kb images and assigned them as “Featured Image” for each post.

      Plugin creates an image, if the first image in the post is externally hosted. The interesting thing you said, that they all have the same “picture” name. It is hard to tell me without looking at your setup and given URL, but probably each of your post has first “picture” image. And may be you should try changing “Image number in the post” in plugin settings to skip this first strange image. But that is only a guess, providing a link would help to look closer at your posts.

    • http://moldnews.eu serhio

      you can see par example this one

      http://moldnews.eu/page/4

      previously, I have, mainly, external images as first images.

    • admin

      Serhio, the given link is not opening – “Maintenance mode”. I was able to open your old posts in google cache and found that your images are from different external sources. I tested some on my setup and “Featured Image” was created correctly from them. Please make sure you are using the last version of plugin (0.7), that your PHP is 5+, that you have enabled CURL library and you have enough space on your local server for downloading images.

    • Ron

      Mary, the Generate Posts Thumbnails plugin did not work. I did not get the Overwrite checkbox. I also didn’t get the progress bar.

      When I clicked to start the process, nothing happened except the button was greyed out.

      I tried using the Regenerate Thumbnails and Auto Post Thumbnails plugins with no luck. The Regenerate Thumbnails plugin broke my site.

      Does the Generate Posts Thumbnails plugin work on multisite? I’m using that plus the latest WordPress, 3.1 Alpha.

      Also my sites are hosted locally, so I am controlling the server. And all of my images are external.

      I also deactivated other plugins that might be causing a conflict. Still no luck.

      I’d like to use your Related Post Thumbnails plugin, but I’m not sure I’ll be able to do that.

      Do you have any ideas? Thanks.

    • admin

      Hi Ron, probably the reason is in multisite setup. I didn’t test this plugin in such setup and with WP 3.1 alpha. The same is about Related Posts Thumbnails. I’ll check how problematic it will be to support multisite. WP 3.1 will be supported once it will be released.

    • Ron

      Thanks. I’ve noticed that other plugins have also been upgrading to multisite. I think the man problem there has been with paths.

      I’ve noticed very few problems between WP 3.0 and WP 3.1-alpha, which I am running.

      I’ll set up a single site and try your plugins on it just to see if everything is working on my end.

    • tester

      I dont really understand why this plugin doesnt work like the “best related posts” plugin for pulling the images? I entered the custom field name to /wp-content/uploads/ where my images are stored but it doesnt use them. If it had better out of the box functionality it would be better then the best related posts plugin!

    • tester

      actually that comment was intended for the thumbnail plugin, anyway my point is that needing 2 plugins is cumbersome and there are better methods like i just told..

    • admin

      Hi tester, please read the section with common problems and solutions here:

      http://wordpress.shaldybina.com/plugins/related-posts-thumbnails/#possible_problems

      With Custom field you need to make sure, that you selected “Custom Field” as Thumbnails source and you are using exactly the same name of Custom Field in plugin settings, that you are using on Post Edit screen to assign thumbnail for post. This plugin was intended to be used with new WordPress feature – “Post thumbnail”, I added Custom field support lately, and you need to configure this plugin correctly so it will work with Custom Fields.

      Your “Generate Thumbnails” plugin is awesome, and I’m using it on a project right now. The script kept stopping at 66% for me. I added some logging to it and figured out there was an external image causing issues (almost all of the images on this particular blog are external, but this one in particular was causing the script to stall). I downloaded the image myself and manually created the thumbnail.

      I’m writing you to let you know this, because I saw someone else comment about the issue. You could add some logging to the script, have it check itself to see if it is stalled, then stop and spit out the log file data to the user. That or have it timeout on and print a report at the end. It’d be easier to find the problematic images that way.

      Just some thoughts for you to consider. Again, you saved me oodles of time by already writing this plugin. Much appreciated!

    • admin

      Hi Guillermo, thank you for this information. Yeah, this is a common issue, and I couldn’t reproduce it. Something with external hosted image. I’ll add some notifications. Thanks for letting me know.

      Hi Roshan, I first thought it was “Related Posts Thumbnails” thread. This plugin actually generates thumbnails and stores them in wp-content/uploads/year/month for each of your post the same way WordPress does it. I had no experience with photoshelter. I suggest you to test it on test server.

    • http://blog.roshancrasta.com Roshan

      Hi, your plugin’s great. I use it in some of my blogs. But I have a problem with 1 of them:

      I have a blog at Byethost.com. I tried to use your plugin to get thumbnail from 1st image of posts, but it didn’t work. Here’s the blog: http://comptips.tk

      I thought it causes by chmod and checked it, but it was ok. I haven’t found any reasons though.

      This problem is strange, because I’ve tested (and it worked wonderfully) in my localhost, and in another blog at Bluehost.

      Please help me. Thank you.

    • admin

      Hi Rilwis, probably theme on your new blog does not support post thumbnails. Please see the list of possible problems: http://wordpress.shaldybina.com/plugins/related-posts-thumbnails/#possible_problems
      If this does not help, please enable developer mode in plugin settings and let me know. This plugin does not create thumbnails, it is using already created thumbnails based on theme settings, so the problem should be in theme settings, not file system.

    • http://www.deluxeblogtips.com Rilwis

      My theme is Arras Magazine theme, and it supports thumbnail. The link you gave is used for Related Posts Thumbnails, not for “Generate Post Thumbnails” (GPT does not have plugin setting page). Anyway, I’ve read all problems there, and can’t find one related to my situation :( .

    • admin

      Hi Rilwis, yeah sorry, thought this comment was to other plugin. How is it not working? Do you see an error or it stops after some percent? Sometimes problem can be in external images, if plugin can’t connect to external service for some reasons, of there is not enough space on server to store images.

    • http://www.deluxeblogtips.com Rilwis

      No, it doesn’t show any errors. Everything goes as if no errors.

      The external images are ok, because I tested with my localhost, the plugin worked. But in my host at Byethost.com, it doesn’t. The space on server is still enough, too.

      I tried to look inside the plugin, and the code seems to be ok. Wondering why it happens? Is there any “hidden” problem with my host?

    • admin

      The only thing I can think of is that php settings on that host do not allow to open external URLs for security reasons.

      No it isn’t. The cURL works well.

      I did checked the Auto Post Thumbnail too, which have the same functionality, but got the same result.

      I’ll figure it out later. Thanks for your responses.

    • http://www.deluxeblogtips.com/ Rilwis

      I found the problem! And it really sucks me up!

      The host cannot use file_get_contents to get file contents, even this function is enabled! So the image content is always empty, then no thumbnail is created.

      I did a quick fix for you plugin, just interchanged the order of executions of file_get_contents and cURL to make cURL go first. And everything goes fine!

      I can’t explain the problem, this is the 1st time I meet it :)

    • admin

      Rilwis, thanks for this information. I am checking php setting before using file_get_contents. May be this is not enough. I’ll probably let the curl go first then.

    • Paul

      Is there any way to setup a cron job to run this script?

    • admin

      Hi Paul, if you write a script that will call process_images function of plugin class for each of posts, you can put this script on cron job. But why do you need this? May be you need this plugin http://wordpress.org/extend/plugins/auto-post-thumbnail/ ?

    • http://www.dereut.org reuldereut

      Good day. I see strange behavior from this plugin. It does run till 100% but does not generate any thumbnails.
      Just the name of the picture shows instead of the Thumbnail.
      if I right click on the name of the thumbnail, it show :
      http://www.dereut.org/wp-content/uploads/test2-60×45.jpg.
      I have a “test2.jpg” in the Uploads dir but I do not have a “test2-60×45.jpg”
      I have been looking for this thumbnail in all subdirectories under Uploads but it does not exist.

      So the plugin thinks it created thumbnails but in fact it did nothing !!
      a pity, It would have done my day!
      thank you for your help.

      Hi reuldereut, this is a strange behaviour, I meet this first time, I’ll try to look what can cause such problem. If you set thumbnail on Post Edit screen does it work as supposed for you?

    • http://www.dereut.org reuldereut

      Good day, I can use the “set feature image” or “set thumbnail” and it does work. the strange thing is that it tries to upload a thumbnail image which is not in the upload directory!.

      Hello. First off I would like to say this plugin is fantastic it works for everything I need. I do have a question for you, is there a way to set up a cron job for this instead of manually pressing the button? There are times when I can not be in the dashboard and the pics look as if they are broken.
      Thank you in advance.

    • admin

      Hi Charles, there is no way to do this using plugin settings. You can use plugin class method in your cron script.

    • Andrew

      urldecode($image) may be the solution
      would probebly need urlencode again before uploading
      I am experimenting right now – its fun because i dont know php at all :) )

    • Andrew

      solution found, posting here for you so that you can test and verify it solves the problem of externally hosted, linked images. that may contain non-english, multilanguage UTF-8 international characters in their file names,add one line to RAW decode url

      $image = rawurldecode($image);

      raw url decode solves the problem completly and generates valid thumbnails that ALSO are keeping in their filenames the whatever meaning of the original file name

      It took me 2 days since i do not know php and i was blind testing things i could find in Google :) …You can delete all my posts after reading
      Cheers!

      Hi Maria,
      I am unable to generate thumbnails. I am using a theme called Gemer (http://wordpress.org/extend/themes/gemer). The script is running fine, but no thumbnails are being generated. My site is here http://journalism.rutgers.edu. Grateful for any help.
      Many thanks in advance.
      Regards,
      Santanu

    • admin

      Hi Santanu, I checked your website and can see that images are not shown in browser for all posts, may be this is the reason.

    • Santanu

      Hi Maria,
      Thank you so much for your response. I did insert images into each and every one of the posts. However, thumbnails are still not being generated for the home page: journalism.rutgers.edu. However, there is no problem with thumbnail generation for the category archive pages, for example: https://journalism.rutgers.edu/?cat=6. Do you have any reason why this might be happening. Also, your plug-in instruction talks about assigning a number to an image: does this just refer to the order in which they have been inserted into the post?
      Sorry for the bother.
      Santanu

    • admin

      Hi Santanu, probably because of security reasons PHP can’t access https files. I can’t even see all your pictures in my browser for security reasons via SSL. Try using normal http instead of https for your pictures urls.

    • Santanu

      Hi Maria,
      Many thanks for your help. The issue has been sorted for now. I will let you know in case I encounter any problems in the future.

      Can one of you please say where and which EXACTLY code we should add to the plugin to make it work with NON-LATIN characters?

      Hello and thanks for the thoughtful plugin. However, I misunderstood the plugin function and I need to remove all generated thumbnails from posts now. It does not look nice at all since I place post images upper left and now they are redundant.

      Furthermore, I only wanted to generate thumbnails in my sidebar for recent posts.

      Please advise how to remove your generated thumbnails. Simply deactivating plugin does not help.
      Thank you for your help.

    • admin

      Hi Debra, this plugin only generates thumbnails and it does not remove them. You can remove them manually, by clicking on “Remove thumbnail” on Post Edit screen.
      If your theme uses this featured thumbnail to display it somewhere, where you don’t like, you can just edit your theme files to remove this thumbnails from posts page. This is new useful feature and lots of plugins using it, so it is better practice to have that thumbnails for posts.
      Anyway thanks for such information, I’ll try to upgrade this plugin to add removing feature.

    • Lucas

      Hey Maria,

      Thx for this plugin. I had no problems generating thumbnails for my old posts. However, any new post I publish does not generate its thumbnail… is this plugin not supposed to? does it only generate thumbnails for old posts?

      Thank you in advance.

    • admin

      Hi Lucas, yes this plugin only works as a tool by pressing a button, there is no automatic work behind.

      thanks for sharing n for your hard work
      btw, i use it and didn’t work for my site :(
      i’m just a newbie

      and if i’m not wrong, your plugin automatically generate custom field and thumbnail value each post, is it?
      but, why i can’t see the value if i checked in edit post page?

      thanks before

    • http://apple-storm.co.cc hans

      nah
      i use your related post plugin
      and it displays thumbnail perfectly
      even i use post thumbnail as source
      the problem is i can’t see the thumbnail on may post
      any help please?

    • admin

      HI Hans, it does not generate custom field. It assigns first image as “Featured Image” (it was called Post Thumbnail before) for each your post. You can read more information here http://markjaquith.wordpress.com/2009/12/23/new-in-wordpress-2-9-post-thumbnail-images/

    • admin

      Hans, the only problem I can think of is that that may post does not have related posts.

    • http://apple-storm.co.cc hans

      thanks for your very quick reply

      what i mean with the second comment is: thumbnail generated from “related post” plugin and “generate post thumbnail” plugin are exactly the same?

      “Post thumbnails

      By selecting ‘Post thumbnails’ as a source for thumbnails plugin displays post thumbnails depending on your WordPress settings. Your WordPress theme may or may not support WordPress Post Thumbnails feature introduced in WordPress 2.9.”

      what happen in my site is, thumbnail from “related post” can display nicely but thumbnail from “generate post” can’t display

      try on another of my blog and it works!! :D

      it generated featured image
      and we can see it on edit post page

      i just think it was because of my theme

      if my theme doesn’t support this feature, there will be no featured image panel on my edit post page, right?
      my theme has shown featured image panel on my edit post page, but without featured image on it..
      try to regenerate with your plugin but still same result :(

      do you have any idea what’s going on?

      finally i can make it
      my problem is my theme
      my theme generated thumbnail automatically from thumbnail custom field
      then i manually change the code to get url of thumbnail generated from your plugin

      ID), array( 720,405 ), false, ” );
      echo $src[0];
      ?>

      and finally it displays on my blog

      After upgading to wp 3.1 it won’t create new thumbnails. There’s no status bar and the plugin only says “Please wait until the process is finished. This process may take up to several minutes, depending on the number of posts and server capacity.” but it doesn’t do anything.

    • admin

      HI muetzenvariete, thanks for the report, I am gonna test it with WP 3.1 and probably fix this week.

      I installed the plugin and ran the script, but nothing appeared in the live log, and it looks like it did not generate any thumbnails. Any suggestions?

    • admin

      Hi Chris, do you see the message, that Javascript should be enabled for proper plugin work? If there is nothing in Live Log at all, that is more likely Javascript issue. Make sure it is enabled in your browser. I tested this in latest versions of Chrome, Firefox, Opera and Safari, where it worked fine.

      Hi Lee, the last version 0.8 of this plugin is supposed to work with WP 3.1. The v0.7 was tested at WP3.05, may be you should try it instead:

    • http://www.Tradersbonanza.com YeOldGoldNugget

      Hi,

      For users of this plugin that have already run the ‘generate thumbnails’ and thus have generated all their thumbnails but don’t want to go through the entire generating process again after adding new posts there is a quick fix.

      When for instance you add several posts without setting a featured image or when using external urls in those posts you can adjust the php code so it will just loop through the last couple of added posts.

      This saves a whole bundle of time.

      In plugin-editor.php?file=generate-post-thumbnails/generate-post-thumbnails.php

      edit the following sql query as following :

      old line
      $posts = $wpdb->get_results( “select ID from $wpdb->posts where post_type = ‘post’” );

      new line
      $posts = $wpdb->get_results( “select ID from $wpdb->posts where post_type = ‘post’ ORDER BY post_date DESC LIMIT 10″ );

      This makes sure that the script loops through only the (order by post_date) last 10 (limit 10) added posts and takes just those to generate the thumbnails. You can set your own limit of course.

      Might be a suggestion to the coder to offer this as a choice in her plugin so users can select how many recently added posts they want to generate thumbnails from instead of having to go through the entire database each time

    • admin

      Hi YeOldGoldNugget, you can use this plugin http://wordpress.org/extend/plugins/auto-post-thumbnail/ if you need to create thumbnails for every new post.

    • http://www.tradersbonanza.com YeOldGoldNugget

      Hi,

      Thanks for the response but your plugin will do just fine for now. Especially now that I have found a way to only generate thumbnails for the last few added posts.

      Served me well this plugin! Thx for that.

    • admin

      Dhananjay, I can’t understand how thumbnails can be generated for categories page and not being generated for home page. Thumbnails are generated for each post. If you don’t see them on home page and see on categories page, that means that your theme is using them on categories page and not using it on home page.

      Hi thanks for trying, I have tried both Firefox and IE.

      Could it be something to do with Thesis theme? And/or where would I look to see if Javascript is turned off?? Thanks (again!)

    • admin

      Hi Kate, you should see a message from plugin if JavaScript is turned off. It turns on in browser settings. Thesis theme may be the reason if it creates additional layer for post images. I can’t tell this for sure as Thesis is not open source. What happens when you set post image manually in Featured Image block on Post Edit screen?

      Well, just found another problem. It generates thumbnails only from images located in the wp-upload directory. All posts with images located in another directory of the same site are skipped.
      The images directory is located outside the wp installation, but on the same site.

      Thanks.

      Enrique

    • admin

      Hi Enrique, if your post has full URL to that image this should work. I just made a test, I added an image outside my wordpress directory, I created a post with that image with image src=”http://my_server/image” and run plugin and thumbnail and uploaded to wp directory was generated. This should behave the same way as an image stored externally.

      Let me say thank you again. I’m migrating a blog with years of content and don’t want one giant folder with all the images so I tweaked the code a bit and early tests seem to show it’s working ok.

      So far so good!

      Above is what the log is showing, I think its showing 19 published posts, I have a total of 26. Its still stopping at around 30%. Not sure if my images are all showing as thumbnails, as it stopped at 30%?

      Thanks for helping me sort this out, you must be very clever to be able to design your nice plugin!

      Thank You!

      Paul, plugin can’t translate images from videos, you need to set Featured Image manually like here: http://wordpress.shaldybina.com/wp-content/uploads/2010/05/featured-image.jpg

      Probably, that’s the problem…

      Hi Maria,

      Hope your fine and thank you for your reply.

      I have been trying to suss this out with the videos, seem to be getting closer, but not quite there yet!

      I use vipers video quicktags plugin to upload you tube videos to my blog.

      I finaly found a way of setting the video image manually as featured image, but the image is too small! Please see link :
      http://kohsamui.co.uk/?p=2463

      I am probably doing this wrong and maybe a long way round, but this is what i did: went to you tube tried to copy as the image of the video, couldnt, but could copy as on the first search of the video by google, then I clicked on videos, saw the video didnt go into it, just copied as there.I then saved the image to my pictures.

      I then clicked on set featured image>selected the file from computer> it would not let me select image as thumbnail, only full size. i finished and was left with the small image in the link above.
      I looked at the properties in the image, which says mulberry bmp.

      Please Please Please tell me what I am doing wrong Maria!

      Thank you!

      Hi Paul, I don’t know, I would probably take a screenshot of my video and make a featured image from it.

    • http://kohsamui.co.uk Paul

      Hi Maria,

      I will google how to do a screen shot, hopefully this will work. Many thanks for your help. Your plugin is amazing! Thank you!

      Kind regards,

    • http://notes.shaldybina.com/ Maria

      Stephan B, what do you see in error log when thumbnails are generated?

      Hi Mary, I don’t see the ” Overwrite parameter” parameter on my panel. :S

    • http://notes.shaldybina.com/ Maria

      Juan, I removed overwrite parameter, because its behavior was unpredictable for some people.

    • http://www.facebook.com/jrpianist Juan Ramon Martinez

      Ohhhh great Maria! by the way thanks for this plugin, you saved me!!! xD set a featured image manually was very tedious, but now thanks to you, I don’t have to get boring doing that. :*

    • http://www.facebook.com/jrpianist Juan Ramon Martinez

      Mary, a little sugestion… would be great if you include an option that let us “generate thumbnails” or “remove featured images” of a specified category… or a specified month. it would be more easy to use, because if you have too many posts, that process would delay a entire day because you cant interrupt it.

    • http://notes.shaldybina.com/ Maria

      Juan, thanks for suggestion. I added to my todo this.

      Hello, I’m using Version 0.7 of “Generate Post Thumbnails” and it’s now time for an update to Version 0.8.

      I’m currently using Word Press 3.3, if this plugin doesn’t work can you suggest another…

    • Orphee

      Hello ! That script is very useful, but how can I automatically remove the first image from the post ? coz now, my thumbnails are well generated but the picture still in the post so it’s display twice (in a post view) , I’d like to delete the image from the post .
      Any idea ?

      Thanks in advance

    • http://notes.shaldybina.com/ Maria

      Orphee, probably your theme display featured image. You can remove featured image tag from your theme template.

    • Orphee

      Hi Maria, thanks for your answer. But my theme displays everything great, the only feature I’m looking for is in order to remove the image from the post, once it’s been auto generated as thumbnail, then I will not have thum + image in my post but only thumb.
      I hope I’ve been more understandable ;)

    • http://notes.shaldybina.com/ Maria

      Orphee, I guess, then you need to edit your posts to remove image from there.

    • Orphee

      That is what I was affraid of :(
      I will find an other solutions (too many posts to edit ^^ )
      thanks for your time

    • http://notes.shaldybina.com/ Maria

      Yeah, probably you need a script to parse your blog posts content and remove first image.

    • Lorina Daiana

      Mine keeps staying at 0%, I’m guessing it’s cuz I have so many posts up.. I was trying to do this so that the Related Post Thumbnails plugin would work. It use to work but for some reason it doesn’t show the images anymore.. unless it has a featured image on the post.. any idea what I can do? I honestly can’t find another plugin that I like better and would really like this to work
