"GIMP is used to process digital graphics and photographs. Typical uses include creating graphics and logos, resizing and cropping photos, altering colors, combining multiple images, removing unwanted image features, and converting between different image formats. GIMP can also be used to create basic animated images in GIF format. It is often used as a free software replacement for Adobe Photoshop, the most widely used bitmap editor in the printing and graphics industries... from Wikipedia."
"GIMP originally stood for General Image Manipulation Program. Its creators, Spencer Kimball and Petter Mattis, initially started GIMP as a semester-long project for a class at the University of California, Berkeley...read the ancient history here."
