Image cropping with PHP and Javascript

By far, this is some of the most valuable javascript code I have seen for a while. Walter Zorn has written various libraries to drag & drop [1] layers and also to draw graphics [2] with javascript. At least the jsgraphics library is published under GPL; for the others I would propose to visit the website of Walter and ask himself regarding license question.

The image above show the result of an implementation of one library together with some PHP image handling which was done by Andrew Collington [3]. It was very easy to implement it into my WordPress Image Handler.
