I have some images in a photo album type thing of charts with a black
background. Some users have complained that when they print this
they use a lot of ink. I was wondering if it were possible to convert 
an image to black and white (b&w only, no grayscale) and then reverse
it so the background will be white. If this is possible what's the best 
way to go about it? Thanks.
