GIMP is a open source image manipulation tool and freeware program to edit images and creating simple graphics. It has good set of features to help user to design graphics. However, Gimp cannot be compare with complex photo editing like Adobe Photoshop because one is open source and another one is commercial product.
However, I find it difficult to use the feature of drawing in GIMP especially who window user like me. It will take some time to master the drawing skill in GIMP. Once you get used to the software, you can create high quality graphics using GIMP.
