Hi Cliff! That's a good question and it's a project I keep meaning to work on, but I haven't. I think the easiest way is to use the editing feature in Photobucket or Picasa. Open each picture that you want to post somewhere and click on 'edit'. Under 'edit' you'll find 'add text'. Add your name or other identifier. Do the text color in gray and set the background to transparent. Save it and you're all set.

I can't get Photobucket to show ALT symbols, but if you can figure out how to do that (maybe type it somewhere else and cut/paste?) then you can add a copyright symbol (ALT 0169) too: ©

Hope that helps!
