FWIW, my photos are all in the cloud in Yandex.Disk but they are also on the computer as well, as you can download a desktop app, so no fear of losing them, also you're not then dependent on a wifi connection to see them. You can also add the app to other computers to view the same pictures. Syncing is fast and flawless.
For those who haven't heard of Yandex, it's the Russian equivalent of Google. I don't recommend their Mail, though. I tried it and found it wanting.
You get 10GB storage space with a free Yandex.Disk account, plus an additional 32GB if you agree to photos taken with your phone camera to be automatically uploaded to the cloud. As I scarcely use my phone camera, my preference being my slr or my compact, I am quite happy to have the KGB examining them in exchange for 42GB free!
