Make sure that the picture you supplied falls within the law as to relevant size. I believe that a graphic representation of a negotiable instrument, including tax and postage stamps, is 150% or greater. Don't take my word, check for yourself. Wouldn't be the first time I was wrong.
Xerox might have something on their site on that subject.
