here is a painting demo where you can save stuff as a .paint,
it is a bit rough but I will work on improving it when I get back.
(line to instead of put pixel, maybe however many pixels you want saving, ect.).
the smiley face represents weither that is an existing .paint file,
if it is a sad face it is not an existing one(as you are typing stuff out)
if it is a happy face it means the file exists.
(sorry, no time for a pic. )
