The GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages.
It was first announced on comp.os.linux.development.apps on November 21th 1995. So GIMP is having it’s tenth anniversary this year.
