[wplug] Confirmation Numbers/Text

[Rick Reynolds]

If you're talking about PHP based code, there is something called the  
GD library that is used to create simple versions.  I use it in a  
wordpress installation I admin.

Maybe other folks know about libraries that do more complex challenges  
(with swirly looking text, for instance).

Thanks,
Rick Reynolds
