no matter how many protection schemes you can dish out, if someone really wants the image and they have a reasonable degree of know-how, they will get it. About the only way you can safe gaurd is by not posting at all. Many people however, really want their work on display. So another thing to do would be to get your own web space and post on your own gallery, as would-be image thieves go to the big sites where there's a large volume of images to gather. If you're able to build up a good reputation with your own site, it will last much longer and speak much louder than a renderosity/deviantart account. just a few cents, and just a thought. I probably won't evencheck for replies, so I hope i offended no one.
