Taking a Snapshot with Webcam

Hi everyone,

i want to give my students the option take a snapshot with their webcams at the end of my course. This picture should then embedded in the certificate, which they should also be able to print out. I could print out the slide of my choice with java script through a button.

But i am having a hard time with commands like opening the Webcam; taking a snapshot through captivate; saving the File after that etc... via Button. The existing Javascripts on the Internet, does not work in Captivate (Copy/Paste). I am not a programmer, thats why the problem its me for sure=) 

Is there a script to do that?

And in general, is there a Captivate Java script library or something like that that you know?

Thx a lot
