Hi Qaysar,
You can validate it using jQuery and any of its ajax methods, however it will not reload the image so if there is a problem with the form input, the image will stay the same, unless you use iframe to store the image and reload it when there's a problem with the input - I've never tried it really, but I think this could be done this way.

Hi there,
after implementing you're captcha, I get the invalid message everytime. I even used you're files and I still have the same problem. Why is that? Can you help?
