Gimp.app is a self contained appication bundle of the GNU Image Manipulation Program [a powerful image editing application and rival of Adobe Photoshop] for Mac OS X. It requires Apple’s X11. Gimp.app is droppable, uses the gimp-print package built into OS X, and uses the system’s default web browser for help and web browsing requests.

Pros: This application is amazing! The X11/OS X integration is nearly perfect, the features seem limitless, and the learning curve is similar to Photoshop.

Cons: Gimp.app currently does not respect the Dock (application windows can be partly displayed behind the Dock making certain areas unusable). There is no word on whether this is a Gimp.app issue or an X11 issue.
