They put it best perhaps:
A ridiculously easy-to-use PHP script for resizing images the smart way.
The major advantage of this script is that it allows me to resize and crop any image on my website without touching the actual image or writing any code.
I upload each image once at a high enough resolution and can then reuse it at any size I want, anywhere I want. It doesn’t matter if the images are in a post, on a page, or in a template file–it just works.
A few tests on a local box and it works! Check it out here: Smart Image Resizer.

That looks really handy to add into jquery sliders that insist you upload images that are exactly the right size.
