WordPress themes need thumbnails in different sizes and they even let the user to change those dimensions. 
But WordPress has a problem: it does not regenerates the thumbnails when new sizes are registered.
Thumbnails intercepts the request by themes or plugins to WordPress to get a specific thumbnail, generates it and caches it on disk. 
Efficiently, it produces a perfectly cropped image, with the right dimension avoiding unpleasant stretching.
Thumbnails does not modify your blog or your media library. When deactivated the blog returns to its old behavior.
The second important feature is the autoselection of featured image for post which are missing it. 
You can choose between the on the fly selection without persist it or, for better performances, to persist it once selected.

Theme developers can find instructions to use it (no code tied to Thumbnails needs to be written!).

Thumbnails

This plugin solves my problems with the WP thumbnails, thanks Stefano!

The one that solves my problem

I re-use my post thumbnail images in various ways, so I like to upload them full size, and I need the software to resize them as needed. This plugin does exactly that for me.

It performs its magic transparently and makes my pages a lot lighter. Highly recommended.


Amazing

Autoselect the featured image and creates pixel perfect resizes on the fly without regenerate all the thumbnails.

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.
