Have you taken a look at this site?http://www.captchacreator.com/v-howtoinstall.html
It was the first thing that came up on google
, so sorry if it doesn't help hehe
You could also try this, It's a form of captcha, it's answer a question and get in.
The freeware version is limited in options but still works.http://www.hotscripts.com/Detailed/68995.htmlImage of it in action.
You can try installing that in addition to your form.
