We just add a cool new feature to doodlekit™ that lets users upload their own header image for their layout. The obvious problem with this is resizing and cropping images is a pain, even if you happen to have photoshop. There's a better way. I knew I could do the cropping with RMagick, but how do I know what to crop? Enter DEfusion's JavaScript Image Cropper UI. This was just perfect, as it uses prototype and scriptaculous, which I'm already using through Rails. Not only that but it supports ratio constraints, which is very important for my purposes.
