Is there any CAPTCHA plugin or module i can use with virtuemart? can anyone point me in the right direction? THanks
Yes there is, you can use Security Images component to set captcha for Virtuemart. You can look more detail in HERE. I have use it on my website and it's working great. This is great component that support captcha on many components not only Virtuemart. Remember that your server must installed with GD library or it will not work.
