Symbal Art?

I've seen so many pictures that are clearly screenshots or uploads when people chat.

How do I do this? I want to upload an image for my Alliance flag.

Bumping because I still want to know.

Still wondering. Anyone?

You basically use software that allows you to overlay the picture you want to copy in a semi-transparent state over the game window and then recreate it using the shapes and stuff in the symbol art editor.
