Flash SWF Snapshot to JPG

I am in search of a “simple” way to implement the generation of a JPG from a Flash SWF housed within an HTML page. DETAILS: Once a visitor has assembled draggable objects within the SWF, and to their liking, I would like for them to have the ability to click a button that would render a JPG version of their layout. Hope this makes sense. I have found source codes online, in conjunction with PHP scripting, but am struggling to make this work.
