I love to share photos on Facebook, but it is not my photo storage solution. I have had entire albums of photos get deleted by Facebook.
Recently, I met two people who had their accounts hacked by someone & then the hackers started posting terrorist propaganda on the person's Facebook page. All of a sudden, they were banned from Facebook and their account was closed.
What does this mean? Well besides missing out on being connected with friends and family... it also meant that they lost all their photos stored in their account. Facebook wouldn't let them in to get their photos.
Please consider FOREVER permanent storage to back up your photos.
