GIMP - A Free Software Graphic Application

GIMP is a free and open-source graphic design program that can be used for photo editing, image composition, and image creation tasks. It was created by Peter Mattis and Spencer Kimball to provide a free alternative to commercial graphic programs. GIMP has various tools for painting, drawing, and image manipulation. It supports layers, channels, transformations, and plug-ins for additional functionality. While originally developed for Linux, GIMP is also available on Windows and Mac OS X.
