What are you trying to achieve? * Are you looking for visible or invisible watermarks (steganography, ala Digimarc et.al.)?
* Are you looking to have on-the-fly information embedded? On a per-user basis? * If "yes," how do you plan to keep track of that information? And if "yes" to the latter, have you considered the privacy implications? All that being said, the practice of visible watermarking is quite common and seems to be a default for the "proofing" interfaces of various online photography services (the people that take photos at equestiran events, running races, etc). Be careful, however, because you can't claim copyright on that which you don't have copyright, and a watermark can be interpreted as such a claim (why else would you have one?). Note that you will probably need to pay licensing fees for invisible watermarking technology that (a) works and (b) doesn't violate patents. I can't say what does and doesn't violate patents (that's by definition for a judge to decide) but that is an area of IP that has been heavily covered over the last 10++ years...
