Hi
 Im using CB with DeathByCaptcha and collecting samples images with their results.
 Whats a good amount of samples to use fixed result hash filter for an image type like this?
 
Charset: 123456789abcdefghijklmnopqrstuvwxyz
Length: 6  chars
 Maybe 100.000 images could help. Right?

This is however not the same when a captcha is generated. In some rare cases it is when there is no noize or always the same static noise. But if you see nothing like that and random noise/char translation, then it makes no sense to use this.
