Suggestions that I think are along the lines of what you're looking for and that have yet to be posted:
-legit pic of galfond's nyc apt w/ slide
-fwf dressed up in ridic outfit holding 6figs+ in bellagio chips and cash, including 2 25k flags in his teeth.
-traheho w/ his "typerky" license plate luxury car
-screen captures from some of the cardplayer high stakes living eps (Greenstein, Elezra, and Robl come to mind), as well as other random sick grinding setups (ie 2 30" monitors in a really baller apt looking out on a nice view).
