I have a ton of cards that I want to scan and archive, but it drives me crazy when the cards aren't exactly square when I crop them. So I spent a ton of time trying to orient them exactly straight on the scanner, which is frustrating and time consuming. I'd like to be able to just thrown them on the scanner and then straighten/crop them on the computer, but at the moment I'm just using Paint, which only lets you rotate 90/180 degrees.

Can anyone recommend some basic photo/scan editing software that has a micro-orientation tool that will let you square things up perfectly before you crop them?

Thanks!
