[Spidey]

Hey i was wondering if anyone could help me out. Can someone tell me how to make an avatar on imageready/photoshop from one picture that zooms and pans from different parts of the pic. Simlar to this:

http://img.photobucket.com/albums/v333/Lee_san87/mnhysx4.gif

would be greatly appreciated. I can't figure it out for the life of me.
