Hello,

we are currently implementing the Authen/Captcha validation scheme into a
registration form. been searching Google to locate alternative images that can
be used inplace of the default images used by the module, but without much luck
locating them. Does any one know where these type of images maybe found, or if
someone on the list my have create their own and my wish to share them :)

TIA,

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. :)
