The best way to watermark and trace

http://www.digimarc.com/watermark/mypicturemarc/

Using Photoshop on my Mac I go up to the top tool bar and go to filters, then scroll down and sellect Digimarc and embed a watermark. Sign up to the the DigiMarc service.

Then go to http://www.digimarc.com/products/imagebrid...der/default.asp and using their MarcSpider you can track to see who infringes on your copyright and where your images are being used and infringed upon.
