Software forum I know.. I need an answer quick though 
I'm trying to edit a scan of a $100 bill to place someone's picture in the portrait circle, and I'm not sure exactly how to do it. I figure the easiest way would be to cut out the oval and just put the picture on a seperate layer below the dollar, but I can't figure out how to cut the center out so it's transparent and the lower layer can be seen through it. I'm not sure what tool to use or how to get a nice clean trace around the oval (if it's possible). Can anyone help a noob out please?
