There's not a lot you can do to protext images really, unless you want to put a big old copyright symbol right in the middle of the image, which some people do on stock photo sites. I'm sure I've had images stolen, we all have. But when it comes down to technicalities, I have the wire frames and source images used to create the image, so I can prove my case should it go that far.

Talent is God's gift to you. Using it is your gift to God.
