I'm trying to find a captcha with the following features:
- Easy to read. Some are very difficult to read and near impossible for dyslexic users
- Image refresh option
- Calls and response (success and fail messages) handled with Ajax so the users isn't forwarded to a new page
I'm using PHP and Jquery. Is there anything out there that would suit my needs? Most I've found forward to a 2nd "response" page, which I woud like to avoid.
