Gimp is a very powerful piece of software. Marques uses this program for all of his graphics on his site instead of using the expensive Photoshop software. You can do anything with Gimp that you can do with paid alternatives.
It is a raster editor, which means that it performs operations directly on the pixels that make up the image, and not a vector editor. Other (proprietary) raster editors include Adobe Photoshop, Jasc Paintshop Pro and the humble Microsoft Paint. An alternative free editor is the KOffice project, Krita. Users wanting to edit photographs will certainly want a raster editor like GIMP. Graphic designers and illustrators may prefer a vector editor depending on their tastes.
Gimp is a fantastic alternative to Photoshop or other titles you hear people raving over all of the time. It’s great for everyone from beginners up to experts and will be able to handle any project you can dream up.
