Help

HI
I am quiet new to flash and have been trying some of the tutorials on these websites, they are great and are very helpfull, I am having troubles modifying the text mask: that follows the mouse to adapt to something other than a text

I am trying to get it to work for an image i was wondering whether there is a way to do that, i want the mask essentially to work like an torch light, but am unable to get that effect no matter what i try.

I was hoping somebody here could help me.
