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
-nycballer's lambo
-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).
-random people celebrating after huge tourney scores w/ piles of money in background (ie raymer, hachem)
i put "poker ballin" into google images, and this was one of the first images that came up:
also, if you do this search, you may want to turn safe search back on. there were a few really disturbing and hard to explain nsfw images that came up.
