So you want to make pictures of words for verification?
Make up a bunch of versions of letters/numbers as images and then use them to create a bigger image on the fly?

Really what would be good is to have a bunch of strange fonts. Then a plain image, you type out the letter combination that you want (be sure to keep track of it) and then print the text on the image with the font (use different fonts in the same image even). Then draw a few random lines of a similar color on top of it, or some sort of pattern.

Using a variety of Brush types will probably help too.
