Description

Andrew

This class can be used to generate images for CAPTCHA validation.

It creates a random text with a limited length of letters and digits and renders it in an image using one of several possible TrueType fonts.

Several background images may be used randomly to obfuscate the text.

The class also renders random circles to also obfuscate the text.

The image is generated in PNG format as the current script output.

Security Images  (captcha)
---------------

Author:		A.D.Surrey
Website:	www.surneo.com
Licence:	GPL (Free, use it for anything u wish)

This class implements security images in PHP using GD. 
(GD comes with PHP4).
It also uses custom TTF fronts and background images.

Changes
-------

version 1.3

Text is no longer all in the same orientation, that is each letter
will have a slightly different angle, vertical placement and size randomly chosen.

--------------------------------------------------------------------------

version 1.2

Added an example using the Captcha class with a Contact form

Added more Background Images and Fonts

Replaced rand() with mt_rand()
This just speeds things up a little ,it's essentially the same function.

--------------------------------------------------------------------------

version 1.1

Added a function to create extra "noise" or random dots 
to the image.
