I've also been taking detailed photos of my packing jobs - just in case I ever have to duke it out with UPS claims. Not sure (yet) if that will come in handy, but at least I have some evidence that its not an amateurish packing job when they try to dismiss it as such.
I used to be the largest UPS shipper in my (small) county. In my experience unless you ship an item in a drop tested to UPS standards package you will have little luck with a claim, photos or not.
The package is dropped from from a specified height (I want to say 30 inches, it's been a while) onto all eight corners. Your minimum dimension around the item should be at least one inch in all directions with proper packaging material. Don't use peanuts or low density styrofoam, corrugated cardboard specifically designed for packing is best IMO.
I insure packages basically to protect against loss, not damage. For something REALLY valuable I'd have a UPS store pack it. Then there could be no chance of a claim being denied.
And I totally agree with Mark, the best market for US collectibles is export and it's only going to get better (or worse).
