Me and some friends want to make a present for another friend and we want to put pictures of each of us, e.g., me
into a, e.g., one hundert dollar bill (replacing Benjamin Franklin and adequate color correction)
and as a watermark on the white left part of the 20 Euro Bill
I know I could use online stuff, e.g., https://photofunia.com/effects/100_dollars, but I would like to learn how to do this the geeky and fun way with Mathematica. Besides, I would like to print the generating code also for the present. Any ideas?
