GimPhoto based on GIMP
GimPhoto is a modification of the free and open source graphics program GNU Image Manipulation Program (GIMP), with the intent to be a free replacement to Adobe Photoshop.
It has a new menu layout, new brushes and gradient sets. Its primary purpose is to enhance GIMP in terms of user interface, use of the best plugins and other resources combined with the latest stable version of GIMP. Because the menu layouts are much closer to Photoshop's, adaptation from Photoshop is much quicker than GIMP.Version 24.1 for Windows is with new installer for Windows 8.1 including 7 and new 10.
Version 26.1 for Mac OS X 10.6+ is also available. It is based on GIMP 2.6.8 and needs X11.
