I know how to get Flash working in case you're interested. I'm assuming here that you (and they) are both using Webkit2png. In that case what you do is install Flash ([package-manager] install flash-plugin) then...
Well, the gist of it is that once you have Flash installed you need to enable plugins (-F plugins -F javascript) as well as set the wait ('-w 10' for 10 second wait before shot's taken) option so that the Flash has time to load.

This article helped me quite a bit. Apparently there's a problem with the wait time so you may need to dig into webkit2png's source to fix it. http://gfdsa.gfdsa.org/2012/08/making-web-pages-screenshots-...
