Prevent Automated Registrations

Smallish hack here, basically it emulates Yahoo's, among other's, system of generating an image with a random series of characters that a user must enter correctly into a text box to register. The screenshots will illustrate this well:

Screenshots
----------------
Registration Screen
Results on Failure
Results on Success

Installation Instructions
----------------
See install.txt in the attachment

Minimods
----------------
Text-only version for people without access to the GD library

The font may be customized by taking a font desired, in TrueType format, and uploading it in place of the font.ttf included. the gd image library IS required to use this hack.

If you like it, install it!

Will give it a shot, thanks!

Are the images (in which the user must input the text on it) just created images?

This is a great idea ... I'll try it later, thanks!

Yes, they're create via the gd image library and destroyed once they are used.

And my apologies to slynderdale, I didn't know somebody was in the process of coding this. I saw this request last night and I thought that it might be good practice, so I made it. My apologies.
