[RESOLVED] Random AlpaNumeric code On Form

[Possum]

Hi

I have a Mail to form to get info form users. I would like to have a randomly generated alphanumeric code put on the page. The user has to input this code to be able to post the from info to me.

How can I generate this code and embed it as a graphic in my form

Here is an example (bottom of page)

Any advice or comments always appreciated..
