GIMP uses the GIMP Toolkit (GTK), an advanced widget library created during the development of GIMP. Since its original release for Unix and GNU/Linux operating systems, GIMP has been ported to many major operating systems and platforms, including Microsoft Windows and Mac OS X. Now, 21 years after its first release, GIMP is used by a variety of people ranging from professional graphic artists, to computer hobbyists of all ages who don't want to put down $700 (price as of 2006) for a copy of the newest Photoshop. The project was started in 1995, and its first public release (0.54) was in January of 1996.

GIMP, as a fully functioning image editor, rivals other industry standard software such as Adobe Photoshop and Corel Paint Shop Pro in terms of features such as multiple layers, the ability to resize and re-shape images, cropping, colour manipulation, and so on. Whilst GIMP can edit vector graphics such as SVGs, other programs such as Inkscape or Adobe Illustrator are far more capable. It can be used for editing electronic bitmap images like photographs. GIMP ( GNU Image Manipulation Program) is an open-source image editing program, licensed under the GNU General Public Licence.
