Output images with text for CAPTCHA authentication

This is a simple class that generate images with a random text that can be used to perform CAPTCHA authentication, i.e. verify whether a site user is a human or a robot.

The image may be outputted with given text or a random text generated by the class.

The generated image also contains a few random lines to make it for difficult for robots to use character recognition programs to determine what is the text written in the image.

The image is outputted in the GIF format.

Generate CAPTCHA validation images with reload.

This class can generate images for use in CAPTCHA based validation tests.

It generates an image of a given width and height with a sequence of random hexadecimal digits over a set of random lines.

The digits and the lines are rendered with the same foreground color. The foreground and background colors are generated randomly. The background color is always darker than the foreground color to assure high contrast.

The generated image is a PHP file.

The verification digits are stored in a session variable for posterior verification.
It also supports relaoding the Image without need to reload the base page. The link used to initiate the reload may be customized to any text or even image or button. Now in version 2.5 a loading gif indicator is rendered till the new Captcha image is downloaded.
