Try a few things.... Digimark your images (which is a good deterrant but can be worked around if they really want the pic) Like you did above, put a monstrously big copyright notice across the image (works but looks awful) Try these sites for some good copyright info (always good for posting on theif's websites) http://www.williamsholler.com/copyright/ http://www.give-credit.com/ http://www.whatiscopyright.org/ http://www.alc-web.com/collections/collections.html http://www.greyday.org/ http://www.rightsforartists.com/ and last of all http://www.billybear4kids.com/clipart/original/original.htm I do this stuff for the love of it, and I always get a kick out of seeing my work around the place, but it really angers me when the person who uses it takes the credit for it. Do they understand how long it takes to make an image like that? Do they even care? Someone says that theft of your work means it's great. I say "BLAH!"
