we are currently implementing the Authen/Captcha validation scheme

Aren't they being generated dynamically, taking random test and applying
distortion to the rendered bitmap of that text ?
If you just had a library of, say, a dozen or even a few dozen of these
images, it wouldn't be that hard to automate logging in through the
canned captcha images, once it's known that there is a small pool of
images to identify.
To be effective, I'd imagine they have to be made dynamically. There
should be multiple modules to help do this sort of thing. Have you
taken a look for 'captcha' on CPAN?
We have the Authen/Captcha module already installed. it has it own set of png
alpha/numerical image characters(a..z & 0..9) and 5 backgrounds which it does
generates dynamically random character image display, but was wondering if there
are other images available that can be used, as the module does allow for an
alternative image folder to be used inplace of the default image location it
uses. the default images are a bit plain. :)
