Any photoshoppers out there? Need advice.

Hey guys,

With all the photoshopping going on, I figured I would like to give it a go myself.

Since I can goof with one of the art departments machines at lunch, I don't need to even invest in the software, just gotta figure out how to use it

Any recommendations on what books are good for the absolute beginner? I think they have the latest version, 7.01 down there.

Anyhoo, any thoughts would be appreciated.

Thanks in advance.
