Sorry about your loss of pictures... That is a bummer for sure...
I bailed out from PB several years back and started using the FREE IMGUR... Its been so long ago I have forgot the reason for leaving... May have been they started charging for things??? My use of the IMGUR photo service now is solely for forums and posting pictures...
All of the family photos is stored here on a couple of USB portable hard drives...
All my kids use the cloud for these things now but being old school I just haven't got brave enough to trust the cloud privacy...
