I've decided to use actually Gimp instead of Adobde Photoshop on my Macintosh computer because my cracked licence key has expired, oh fuck ! but what's gimp ? Gimp is a free and opensource image manipulation program under GNU licence. It works under a lot of oparating systems like Linux, BSD, Solaris OS, Macintosh OS or Windows OS. There are full options like photoshop, Layer manipulation, photo retouching, image effect and more plugins ...

Gimp, Just Try it !
