Implementation of Jquery Crop

[eluser]ridley1012[/eluser]
Hi, has anyone managed to implement an upload + crop script suchas the one found here.

Code:

I like the functionality but have tried multiple ways to implement it and can't seem to get it working. something similar to this would be great as I need the users to be able to crop images.
