hehe, well... if your house burns down (hope not)... where are your pics!? Either put them in a safe which is fire AND water proof for some hours or leave a copy at a relative's residence.
I have fire/water proof safe in the cellar, because if your house burns down it will be not that hot in the cellar, but it can turn out to be a swimming pool after the visit of the firemen
Actually you should do this with all important documents but we humans intend to be lazy... myself incuded hehe
Cheers,
