This plugin create rounded corners. Based on:
Apply Rounded Corners to Images On-The-Fly Using PHP and GD Library
The code generates a mask for the top-right corner by drawing a transparent circle over colored background. This mask is then rotated and superimposed on the specified image four times.

Nice one, if you'd like it included in the distribution, why not fork the project on github, add your code, and send me a pull request (http://github.com/iselby/PHPThumb)? That way you can keep original credit for the code, etc.
Otherwise, great work, people can grab it from here!
