The faces are randomly rotated and cropped, so just as one letter can be many images, so too can one face. There are just a LOT more faces to choose from than there are letters.

Mine has only 26 damnit
And I have never seen a captcha displaying just 1 letter, normally is it letters and words making it (26 + 10) 36 per char, so a 5 char long captcha is 36^5 ;)
Congrats on the launch though, it is looking great !
