I have some photos on a linux computer that I would like to add to a Shared iPhotos Album.
So I thought I would log in to my icloud.com account and add them there.
To my surprise, the shared albums are not even listed on my icloud.com account? Why not?
How can I add photos to my shared iPhoto album with a non Apple computer?
UPDATE: My Mac doesn't even show the Shared Albums, even though I use the same account as on my iOS devices.
UPDATE2: I am running MacOS10.13.6
UPDATE3: Thank you @fsb it was indeed an iCloud setting: "iCloud Photo Sharing" that wasn't enabled.
