The GIMP (GNU Image Manipulation Program) is one of the many high visibility Open Source programs and is included with nearly all Linux distributions. It has also been ported to Windows and is available for free to anyone with the desire to download it. Some believe that the GIMP suffers from usability problems and isn’t quite at the same level as Adobe Photoshop or Paint Shop Pro, however that is a matter of much debate.
In an effort to remove at least one of those complaints, one enterprising developer took it upon himself to make Adobe Photoshop users feel at home with the GIMP by re-arranging the menus and naming conventions to match Photoshop as much as possible. The result is GIMPshop and thus far the only complaint related to the work seems to be the desire that the official GIMP follow the same conventions.
GIMPshop was written initially for the Macintosh architecture, but has since been ported to both Linux and Windows.
If you are an old Photoshop hand, but don’t have the money or desire to purchase a new copy, or you might just be somebody looking for a powerful free Image editing program, you could do worse then to try GIMPshop, (Or the official GIMP if you are not fussed with the Photoshop related changes).
