So I attempted a CAPTCHA breaker

he means, you get all of the .jpgs, and hash their data. When you get an image on youtube, download it, and hash it the same way. Now, instead of comparing 20 pixels to another 20 pixels, you compare 1 string to another string.

I thought he was doing something along this line when I first saw the thread. This is a really good idea.

PollFactory - I thought that MD5s were only statistically unique, but that you could in fact have two (in this case) images that have the same hash. Just my thought - I might be wrong.
