Post Thumbnail Plugin

by 6 Comments

This plugin has been retired. It will no longer be supported or updated.

This plugin automatically assigns thumbnails to posts using the Post Thumbnail Interface introduced in WordPress 2.9.

The plugin also has the ability to re-size post thumbnails.

[Most recent Shiba Thumbnail Plugin updates]

June 18th, 2010 – Release 2.2

  • Shiba Thumbnail Plugin is now updated for WordPress 3.0. It should work in 3.0 and 2.9+.
  • Inserted class wrapper around plugin functions, and modularized functions into multiple classes so that it is cleaner and more secure.
  • Shiba Thumbnail Plugin no longer uses proc_open to run the thumbnail generation process. It should now work across most hosting platforms.

Post thumbnails are assigned as follows –

  • Nothing is changed if a post already has a thumbnail assigned.
  • If a post does not have a thumbnail, the Shiba Thumbnail Plugin will get the first image within the post content and assign it as the post thumbnail. If the image does not exist in the Media Library, a new image will be created and added to the Media Library.

Thumbnails will only be generated when you request the plugin to do so by going into Posts >> Generate Thumbnails.

The plugin creates a background thread to generate the post thumbnails, so you can continue using your WordPress dashboard while it is working. However, depending on the total number of posts and pages on your blog, the thumbnail generation process may take some time to finish and will put added load on your blog server.

As a result, it may be best to regenerate thumbnails during a less busy time of the day.

”Generate

During thumbnail generation, the Shiba Thumbnail Plugin will show a list of changes made by the plugin. To get the current status of the thumbnail generation process, at any particular time, go into Posts >> Generate Thumbnails. If you are already on that screen, just do a page refresh.

Below are a list of detailed features offered by the Shiba Thumbnail Plugin.

Shiba Thumbnail Plugin Features

  • Automatically assign post thumbnails.
  • Re-size post thumbnails. This is most useful when you install a new theme that has different post thumbnail size requirements.
  • Clean-up post thumbnails when an attachment image is deleted. Specifically, the plugin will delete any post-thumbnails associated with the deleted attachment.
  • Automatically assign post thumbnails to new posts and during post updates.

Shiba Thumbnail Future Additions

  • The Shiba Thumbnail Plugin will try to automatically assign thumbnails to posts that do not already have associated thumbnails. We may want to allow the creation of posts that are not linked with any thumbnails.
  • Process post galleries while looking for a thumbnail image in a post.
  • Add thumbnails to gallery type objects (created with Media Library Plugin).
  • Integrate post thumbnail functionality into Media Library Plugin.

Note – The Shiba Thumbnail Plugin is free software and may contain bugs. Please make sure you have back-ups of all attachment files to ensure no loss of data.

Shiba Thumbnail Updates

Shiba Thumbnail 2.1

  • The test for an existing thumbnail image has been significantly enhanced, so duplicate thumbnail attachments will no longer be created.
  • We now process relative path images as well as absolute path images.
  • All newly generated thumbnail attachments are now appended with ‘[shiba_thumb]’ so that you can easily locate all of the added files.
  • Finally, image files are tested to see if they exist before resizing operations.

  1. Where does the plug-in save the thumbnail to? I ran this and don’t like the image it chose for many of my posts without images (it chose an ad in the sidebar.) I’d like to clear the thumbnails and start fresh, if possible. Any thoughts? 🙂

    Thanks,

    • Hi Jeff,
      The thumbnails get saved into the regular WordPress Media Library. Just go into the Media tab, and all the created thumbnails should have shiba_thumb in their title. So do a search for shiba_thumb, to get all of the images it created.

  2. hello,shiba 🙂

    i used custom widget. Now im thinking of using this plugin. Before that, is it possible to use this plugin to set featured image automatically?

    Let say, i have an image in my post but havent insert yet. I want this plugin to grab the image as featured image without inserting to the post. Just set it as featured image.

    Is it possible? I tried many plugin but none work.

    Lastly, keep up your awesome work.

    • Do you mean you want to use a chosen image as the default featured image? That is a good feature to have and not too difficult to do. I will definitely need to include it in future updates.

      Currently, the plugin only looks for the first inserted image and uses that.

      Thanks for the great suggestion.

  3. Hi Erin,
    It would all depend on what your want to ultimately do with your thumbnails, what you want to use the custom fields for, and what tools/plugins you are using or plan to use.

    Using the WordPress Post Thumbnail system has the advantage that it is part of WP core and so will likely be adopted into many plugins in the future. I am already using it in my Shiba Gallery Plugin, and it allows me to do much more than I was able to previously.

  4. This is amazing! May I ask, I have a whole bunch of thumbnails with custom fields. Should I make them into post thumbnails with your plugin, or do you suggest I just use conditional statements to display them?
