What is Securimage?
Securimage is an open-source free PHP CAPTCHA script for generating complex images and CAPTCHA codes to protect forms from spam and abuse. It can be easily added into existing forms on your website to provide protection from spam bots. It can run on most any webserver as long as you have PHP installed, and GD support within PHP. Securimage does everything from generate complicated CAPTCHA images to making sure the code the user entered was correct.

Minor Bugfix and Site Updates

Version 1.0.3.1 was made available yesterday which fixes a problem when using the word list feature. If you do not use this or were not experiencing any problems then there is no need to update.
An article about using Securimage with Ajax was also published yesterday, you can view it here.
We have also released a tool which can obfuscate your email address in Javascript code for those who need to post their email address on their website. Check out the Email Address Obfuscator tool.
Version 1.0.2 Released
January 6, 2008 – 10:09 pm
Securimage 1.0.2 has been officially released. It adds 2 new features into the class. The first is being able to use CAPTCHA codes read from a word list instead of generating random codes. The second includes the ability to create audible CAPTCHA codes as WAV files by combining sound files of each letter and number that appears in the character set.
A few minor modifications have been made to have better error handling and fixed an undefined variable warning.
It is recommended to upgrade to for the most features and stability.
Site Construction and Launch
January 1, 2008 – 10:36 pm
Over the next few weeks the Securimage CAPTCHA class available from NeoProgrammers.com will have this entire site dedicated to the development and distribution of the PHP code. The goal is to serve the users better by having a support structure and make improvements and implement suggestions faster. Because Securimage is released under the GPL license and anyone is free to modify the code I would love to see outside contributions to add new features and capabilities to improve the class.
Thank you for your interest in this software!
