You can use the class for google recaptcha as GD would not be available on all the servers but most servers with PHP would be able to run the google recaptcha class.

If you want something that must work without gd, you could take a look at NUCaptcha. The only PHP prerequisite is the mcrypt library. As opposed to a traditional CAPTCHA, the NUCaptcha website explains:

NuCaptcha is displayed as an H.264 MPEG-4 Video Stream that is rendered in your browser in a variety of ways.

GD might actually not be installed on some web servers which is reason enough to first check which image manipulation extensions are available with http://php.net/manual/en/function.get-loaded-extensions.php

GD is available on all servers, it's just a matter of having the PHP extensions loaded. Since PHP does not have image processing natively built in to the language, an extension is the best anyone can hope for.

It's worth noting that ImageMagick is another option, but it's a bit of a pain to get installed.
