On the advice front - try not to ignore blind (or limited sight) users 
:-) I've a friend who often has good cause to complain about web sites 
that are only for what he calls, "sighties"

I'm not sure what is the best way to deal with blind users is though. 
The 2 alternatives I've come across are:

   1. Manual - which is probably not a bad idea for the small number of
      users this will be required for, but is inconvenient even for the
      end user as they have a delay (and you may have to worry about
      spam'ing)
   2. Audio - some image captchas have a fall back to an audio captcha.
      I'm conveniently ignoring the blind/deaf users who are using
      braille.....
