I have tons of family pics on a flash drive and want to have them randomly playing during the upcoming holiday season and when family comes over. I was going to use my ps3 to do this but there seems to be no way to. I have no problems shuffling music but I have tried numerous ways (group by all, making a playlist etc...) to shuffle pics with no luck. Furthermore, I have 2 apps (photogallery and playmemory) downloaded that I thought would help but nothing. I would think that a ps3 could perform a simple task like this but so far sony has proved me wrong. Is there any relatively simple way to do this or an app I can download?

PS - Please, no Xbox users telling me that ps3 is shit, even with this technical flaw I'm still very happy with my ps3, thanks
