GIMP 2.8 is a GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring and much more.
GIMP 2.8 is another important release with lots of new features.
This video gives a small impression of this great free software.
The file format support ranges from the common likes of JPEG (JFIF), GIF, PNG, TIFF to special use formats such as the multi-resolution and multi-color-depth Windows icon files. The architecture allows to extend GIMP’s format capabilities with a plug-in. You can find some rare format support in the GIMP plugin registry.
System requirements : Reasonably x86 hardware and in my experience 2 GB Ram.
Supported Platforms :
-Microsoft Windows (XP SP3, Vista, 7, 8)
-Mac OS X (10.6 and newer)
