I often fake the shots the day after if we were using my models on gaming night. If it's somebody else's stuff then I just make sure I take about a million pictures while we're at it, even if it does disrupt play.
My battle reports come before their enjoyment of the evening!

Actually it's not as if our mob aren't always stopping to chin wag about stuff nothing to do with the game for minutes on end as it is, so me taking pics doesn't really disrupt anything at all.
