For those photographers concerned about copyright infringement of their work, I think the Flash idea mentioned above is a good one. Another alternative is the use of DigiMarc technology (http://digimarc.com) which puts an invisible digital watermark in each image that allows it to be identified and tracked. Some applications like photoshop automatically look for such a watermark in every image and display a copyright notice when the image is opened. The watermark survives some image manipulations such as resizing. They even offer a service that hunts for your images across the internet and notifies you by email if they find any. Of course once you do find a ripped-off image, the watermark doesn't help you any, except possibly to help confirm your claims in court. I am not associated with DigiMarc in any way, nor do I use their service.
