GIMP means GNU Image Manipulation Program. It was first released in 1996 by two students from Berkeley University and it has been getting better and more widely used ever since. This freely distributed program is used for such tasks as photo retouching, image composition and image authoring. It offers all the basic and many of the advanced features of applications like Adobe Photoshop: layers, channels, paths, different painting tools, etc. so it can be a perfect tool for both beginners and professionals.

As GIMP creators say, this software “is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.

GIMP is mainly written and developed under X11 on UNIX platforms, but since basically the same code can be run on both Windows and Mac OX, this application is available for almost every operating system.
