Sooner or later someone is going to come up with a theft-proof way of digitally watermarking an image. Until that time what you could do is only show small unedited thumbnails. For the larger linked image just hack out a chunk in a complex area of the image, say 20 pixels by 20 pixels. If you want the uncut version of the image, you need to apply and have it sent to you. You want to be a filthy weasel and steal it, well, you've got a lot of hassle with PhotoShop to try to recreate the lost area. It ruins the full enjoyment of an image, but so does copyright theft.
