Thanks ever so much for your advice VikingPhotography and Dabhand16
im gonna give some of your advice a try. I think the water marking that you posted VikingPhotography , appears to be the most effective in your post but the File>file info section on cs2 was new news to me, and that will also contribute to my photographs.
I will have to post a photograph you to see what you think and to see if im going down the right track.
