Description:

The (so called) "Security Images" are so popular. Most Internet
software use these in their registration screens to block robot
programs (which may register tons of fake member accounts). Security
images are basicaly, graphical CAPTCHAs (Completely Automated Public
Turing Test to Tell Computers and Humans Apart). This module gives you
a basic interface to create such an image. The final output is the
actual graphic data, the MIME type of the graphic and the created
random string.

The module also has some "styles" that are used to create the
background of the image.

If you are an Authen::Captcha user, see GD::SecurityImage::AC
for migration from Authen::Captcha to GD::SecurityImage.
