The amazing thing is that we already have a image, so they are using
OCR (Optical character recognition)? Maybe harder images would be a

you can use my idea at http://ik.homelinux.org/index.rhtml/contact where
I ask logical questions that you need to understand the question and

arrive at random :)
We already have questions, that didn't help much.
