It seems interesting. I do not need to generate captchas right now,
but maybe in the future.
I have two small remarks after having looked at the project:
- All your examples in the Introduction wiki page begin with "require
'gd' ". It seems useless.
- You always use string.len() for retrieving the length of the string.
Why not use the # operator ?
