That requires more effort than an OCR program.
It requires "more" or "less" effort depending on the problem space and how well the computer has to "see" the image... I'm sure there are "simple" and "harder" OCR-like problems. > Add to that, that every image could present a new problem to decipher > and you have the makings of a formidable deterrent.

I think not... You only have to find 10,000 people who hate MS and give each of them 200 unique images to identify. FOr that matter, the images are coming from Petfinder, according to their blurb... How tough could it be to find the same bytes in an image in Petfinder and then detect the "cat" or "dog" tag on their website -- assuming they have categorized their Petfinder images by species/genus? Methinks a dedicated cracker could defeat this in very short order. -- Some people have a "gift" link here. Know what I want?
