Flash game site is looking for a solution for making screenshots out of flash games, by the players.
Your goal is to implement a method, which will take screenshot of currently running flash game (which is embed on the same page, loaded from the same server).
It is not possible to modify any existing flash game, source code of those flash games is not available. Games are coded in both as2 and as3. It is not possible to install any software to users computer, no browser plugin.

Show me your working example here, which will make a screenshot of the following game:
