Hi!

Just discovered another problem with my latest site for the University of Granada. Their server is a real pain in the ass.

They don't have GD library installed.

I can't believe that.

I can't use DuGris', or any other's Captcha anymore. They require GD library or something related, is that simple.

What can i do?

Googling around, I found an idea: a Flash CAPTCHA. This is a really great idea, but I can't found any to download, just ongoing projects.

So suggestions welcome.

Not sure, but did you have a look at the captcha module from Happy Linux?
More information can be found here.

CAPTCHA from Frameworks 1.10 does not require GD
