Any 3rd party captcha image code inPHP

Hi,
I want a 3rd party captcha image code in PHP thtat deos not create image on server.

I tried recaptcha third party tool But it has bug
If the image contains two words "23 Tiger" and u typed "22 Tiger"
It accepts it. and tht i hvb tested on their site itself
here is the URL
http://recaptcha.net/learnmore.html

Seems like if you put only the first piece of text it would work... weird!

Is there any specific reason you don't want the captcha to be created on the server? Meanwhile, I'll keep my eyes open for one.

@bogey

maybe 22 tiger has been generated (elsewhere) too along with 23 tiger, that's why it got accepted

@httpftp

Its better to generate it on your server and associate with database rather than session variables if you can afford. Because this is a security measure and you are relying on 3-rd party?

lol, it's not like every time you view the page you get 23 tiger or something along that. When I went there it was something like Hassam $16 and I simply submitted Hassam and it counted it as correct.

And if it created 22 tiger elsewhere alongside with 23 tiger, it wouldn't accept that because it tracks the users using the service (As in the ones filling in the form, rather the one who is using the code). I hope I made myself clear.

ok @bogey

you made yourself clear

It seems that recaptcha thing is a complete bug

Yeah... it never used to do that for me for some reason.

@httpftp21: If you are willing to put one on your site I can provide you with the CAPTCHA code with the required resources for it... it works perfectly well... I have no idea where I got it from but it works great.
