Copyright watermark on photos

I just found this:

which explains how to do the above even easier than I've been doing it. This way, the letter size can be adjusted to the size of the individual photo. I've been saving the whole thing as a file and copying and pasting which works, but it's one size and as we all know that does not fit all.
©, BTW, is done by holding down the "alt" key and typing 0169 on the numbers keypad.
