This class can generate images for use in CAPTCHA based validation tests (Completely Automated Public Turing test to tell Computers from Humans Apart). It is an improved version of the Captcha Numbers class originally written by Hadar Porat.
GD2 Problems ------------ You must have GD2 module installed with PHP. If u get imagecreate() not found, it's means you don't have GD2 installed. You can install it easly on windows by open php.ini and uncomment extension=php_gd2.dll line. Also check that extension_dir in php.ini is correct. Font Problems ------------- You must have arial.ttf available for the script to work. If the picture is shown without numbers (only grid) u need to download arial.ttf from http://www.webpagepublicity.com/free-fonts-a4.html. Save arial.ttf in the same directory of the script. Notice it's arial.ttf and not Arial.ttf.
