I got feedback from a couple of folks who had the unfortunate task of going through an insurance claim process. As long as they have receipts, they're fine. Obviously this could pose a problem for some of your items that you purchased years ago but he told me lots of photos that show your item inside the house goes a long way. e.g. This won't work ... Photo of your 47" LCD in a room that doesn't look like anything inside your home.

Generic photos won't work, I know many folks keep a video recording of their home.
