(I know there's another stamp that looks the same, but HEY! here you have with a black background XD)
A stamp for all Gimp users.
^^
Remember, if you can't afford programs like photoshop, you can always use the free ones. GIMP is one of them, and is the one i use(Check my gallery to see what you can do).
By the way, even if you could afford Photoshop you can still use the GIMP. I'm atm annoyed that at work I have to use PS when I would prefer to use the GIMP even there. (And all of my CG art is done with the GIMP, too )
I used both, Photoshop and Gimp.
But i like more Gimp X3
