This morning I woke up and somewhere between some relief and choosing two matching black socks it came to me like a hammer. HE SHOULD MAKE A CUSTOM BRUSH OF HIS STAMP! Like, open 100 files. Select the brush. Select a forground color and a background color. Stamp on the desired spot. Or, if the spot is dark, hit the 'x' and the colors switch places. This is how I should handle it if the pictures were all different sizes. And the stamp could be in one color. It still seems a good idea now I am drinking coffee. Still not sure about those socks though.
