Photo storage /viewing that doesn't try to sync my photos to a computer (making me scared of losing them in a sync mishap) or share them. Electronic equivalent of a shoebox. Snapjoy did this but Dropbox bought them and shut it down. I haven't seen an alternative - maybe the new Amazon photos does this?
I had been looking for this too. Amazon CloudDrive (Prime Photos) does a pretty good job (at least on iOS). Free for Prime members. My only complaint is that the uploading choices are either automatically uploading all photos (which I don't want it doing) or selecting photos one by one. I would like an album level option to upload all photos in an album.
