Alot of people use GIMP. But i prefer to make simple sigs and stuff with photobucket lol, Or theres always MS paint
I use Paint.NET. I think I'm the only one who uses it in this forum lol. It's actualy a very good program, comparable to GIMP or Photoshop. You can find a link in my sig.
It's not comparable. I've had it before. And your better off just downloading GIMP. But I use CS2. CS3 hasn't made any groundbreaking improvements for me to really upgrade.
Photoshop; always used it and always will. You can say whatever you want about "GIMP being a sufficiently purposeful image editor," but nothing comes close to competing with P-Shop.
