monkey_magix Posted April 14, 2007 Share Posted April 14, 2007 Hi, Just wondering what people are using for Captcha if they don't have GD compiled for their php version on their server? I'm a bit stuck as my server doesn't have GD or FreeType. Many thanks Dan Link to comment https://forums.phpfreaks.com/topic/47013-captcha-without-gd/ Share on other sites More sharing options...
Glyde Posted April 14, 2007 Share Posted April 14, 2007 I have read about some people using textual based numbers, i.e. replacing 55604 with fifty-thousand six hundred and four. Also you could do something like this: Each number (0-9) has its own image file, with some random name such as: a4gB6jf5bzloS563.jpg. Every few times your script is loaded, it renames those files each to something different, so there are never any consistent names. Then on your page you could just use <img> tags to display them side-by-size.

kevingarnett2000 Posted April 16, 2007 Share Posted April 16, 2007 You could use a web service for that: http://www.trynt.com/trynt-captcha-api/ You would need to have curl in order to communicate to the service Link to comment https://forums.phpfreaks.com/topic/47013-captcha-without-gd/#findComment-230254 Share on other sites More sharing options...
