Enhanced Captcha Image Verification
Title : Enhanced Captcha Image Verification
Version : 1.1
Coder : Andy Calderbank & Jason Williams
Purpose : Add extra Image Verification to the registration process, using an alternative system to the Captcha system.
Why : It would appear that spammers can now "read" the Captcha codes and overcome the verification process.
This extra feature uses images which are harder for a spam program/bot to interpret than text characters. The user has a choice of 4 randomly displayed images, and the answer is given below. The user must click on that image to proceed, if the incorrect image is selected an error message is shown. The images are randomly shown (from however many are in the directory - you can have as many as you want, just has to be more that 4!) and are automatically created from the images/verification/ directory - all on the fly. Sample images are included with this release, but you can use your own - I recommend using 100 x 100 pixels, in .jpg format and naming the image with a meaningful title (ie A House.jpg) - the extension is stripped so only the filename itself is shown.
To further enhance security, the images are passed through a script which means that none of the images on the screen have file names - and cannot be associated to the question by title alone.
Upload the verification/ directory to your images/ folder - make sure .htaccess and show.php are present - otherwise it won't work.
