Let's say I find a picture, but it's in a square background.
How would I be able to change the background color without messing up the picture? I'm sure the guy who puts images like this on zeldauniverse found a good way to do it, because the picture has a white background in the manual where he scanned it from (he todl me he scanned it, but wouldn't tell me how he changed the background.)
I'm sure this would be easy in something like photoshop, but I don't have the money for a program like that. All I've about got is paint, and that's useless.
Help?
