    Re: php captcha ??

    I'm looking for something more similar to that which Google is using on their own sites:



    And maybe something similar to reCaptcha:



    Except without using their database. The problem with reCaptcha is that it has to use their database for the captcha's, it is not generated within the server you insert the captcha on. It calls back to the recaptcha.net server to get an image. Basically I'm just looking for the style of font (with the distortion) and the slashed line that reCaptcha has. not sure how to do that.

    Maybe this could be useful? http://www.lagom.nl/linux/hkcaptcha/
    Never argue with fools, they will only drag you down to their level, and beat you with experience.

    thanks, very useful, especially the links within that page. I found this page to be really interesting:
    http://www.ocr-research.org.ua/list.html
    It rates most of the captchas that are out there right now.
