What software(s) do you use?

He doesn't make them, he's using NovaSkin's wallpaper maker (you can tell by the obvious watermark) which is free to use.

Honestly I really don't like it when people make these "Profile Picture Making" threads when all they're doing is putting values and images on someone else's original work :/

 Ahhh! I used that a few times but I use blender now
