Captcha Help

[andrewsmd]

I'm looking for a good captcha script (those little randomly generated letters and numbers at the end of a form that you can never read). I have found some on the web and followed the instructions exactly but I can never get the image to show. Does anyone know or have a good one I can use instructions would be nice but they aren't mandatory.

Most captcha`s will require your server to have the GD graphics library enabled. How you sure your problem isn`t because this is disabled?

And if You can't, or you don't want to, have GD graphics library You can use some simple techniques to implement "sort of" a captcha. This is what i usually do for any quick form that i dont want to spend much time securing.

Above the captcha Text box you can say "Type 4+5 in the box below"

Any BOT won't be able to do that/

Yep, I use spam sums too. Another good spam prevention option is figlet. Google it. You`ll find some free classes to use.

Doing more reasearch I discoverd that my GD graphics was disabled for some reason (I don't know why I have PHP 5.2). I got it working, thanks everyone.

I don't know why I have PHP 5.2

Having GD enabled is an option. Having PHP 5.2 doesn't stop it from being an option.
