Thanks everyone. This is why this community rocks.
Simon - So when are you going to give me the blatant plug for your website, huh?
Hehehe... I can't really give direct photo credit because for this project, and all future ones, the snakes will likely be part of a montage, and there will just be the disclaimer "All sample photos used with permission." But, if I ever use a whole, untouched photo, I'll be sure to photoshop in the credit for it.
