Does anyone have any experience using GIMP (Gnu Image Manipulation Program)? I've downloaded it, but haven't installed it yet. I was curious about what others thought of it. For those that haven't heard of it, its the open source equivalent of Photoshop. The main limitation I know of is that it can't do 16 bit images, just 8 bit. It supposed to be able to read some Photoshop plugings, but I'm not sure how well that really works.
