SimpleRecentThumbs is a widget plugin that shows a list of thumbnails from recent posts with featured images, optionally filtered by a category. Other than setting up the widget details, no configuration is required.
The thumbnails are in a widget-standard unordered list. The widget CSS class is widget_recent_thumbs and the thumbnail links are class post_thumb.
Leaving the category field empty will have the widget use thumbnails from all posts; posts without featured images will not be listed. Without a category specified, the “more” button option will do nothing.
Thumbnail size is as specified in the Media settings for WordPress.
SimpleRecentThumbs has no extra requirements and has been tested with the twentyten through twentyfourteen themes.
Development on this plugin has halted. Other developers should feel free to use the Apache-licensed code for their own projects.

Scan and delete unwanted auto-generated WordPress images and save huge diskspace. Delete thumbnail sizes (started or ended with 150px, 280px 300px or 1024px) and move them to a trash folder inside your uploads directory. Preview and restore images from the trash.
Whenever you upload an image, WordPress creates three additional resized versions of that image. This increases your hosting inodes and unnecessarily occupies disk space.
