BTW, the CAPTCHA solution I am using is a modified version of the plugin which can by found on James Seng’s blog. I’ve kept Seng’s method of storing keys in files, but I’ve changed the actual challenge to be much more difficult by using some code from the FirstProductions Human Test project. I suspect that my version is much harder to crack with OCR software than Seng’s version.
Hey, great work! found you through a trackback, would you be willing to share what you changed in his plugin to add this functionality?
