Simple Post Thumbnails


This plugin adds a widget to the posting screen that allows you to add a post thumbnail by uploading an image from your computer or via a URL. The thumbnail is scaled and cropped to the correct size automatically.

Please visit the documentation for detailed instructions on installation and usage.


  1. Make sure that your host has the GD graphics extension for PHP enabled.
  2. Upload the plugin file to your wp-plugins/ folder.
  3. Go the plugin management page and activate the plugin.
  4. Add the p75GetThumbnail(int $postID, [int $width, [int $height, [string $fileType]]]) function to your theme to get the URL of a thumbnail and p75GetOriginalImage(int $postID) to get the URL to the original image.
  5. Go to Settings > Thumbnail Options to configure default values for the plugin.


How do I add a thumbnail?

Go to the posting screen and either upload an image from your computer or enter in the URL of the image in the form provided.

I am getting errors when I try to upload thumbnails, what is wrong?

Make sure that a folder called “thumbnails” was created in your wp-content folder and make sure it has write permissions (755 works). If this folder does not exist, create it.
