Sbox Like Model Button

Hello, how can I make a picture button of a playermodel, like the one in Sbox?

Yes. http://wiki.garrysmod.com/page/Category:SpawnIcon

Thank You!

EDIT: Can I resize and repos the position of the “camera” in spawn icon?

I will be able to change the playermodel with this button?
