Like Dennis, I only use PB for sharing copies, in my case, almost exclusively for displaying the Firebird-related images here on the 1st Gen Forum. Fortunately, all of my photos are in my desktop computer and backed up a couple ways here at home so even if PB eliminates all access, my stuff is not lost. It's just that the photos I have put in the forum will forever not appear here. PB is also now filled with multiple pop-up ads that have to be closed before getting to my file there. I don't really trust "cloud-like" services as a main photo, document, etc. storage and PB is verifying my distrust.
I am now using this forum's attachment feature when I want to share a photo.
