I'm not sure it would be "trivial", but then having never written any
OCR software I have no idea :) You could of course randomise the
picture shown massively, with same 500 different sorts of image (cats,
dogs, people, etc) the task would become harder for sure. Then again,
I do feel this is slight overkill to just avoid a script bot from
registering on your site :)

Best regards,

Richard Davey
