From the developer

Shane Bishop's own description of Imsanity, lightly tidied.

Automatically resize huge image uploads with Imsanity. Choose whatever size and quality you like, and let Imsanity do the rest. When a contributor uploads an image that is larger than the configured size, Imsanity will automatically scale it down to the configured size and replace the original image.

Imsanity also provides a bulk-resize feature to resize previously uploaded images and free up disk space. You may resize individual images from the Media Library’s List View.

This plugin is ideal for blogs that do not require hi-resolution original images to be stored and/or the contributors don’t want (or understand how) to scale images before uploading.
