I have iCloud Photos on my PC as well as on my iPad and iPhone. How do I get a folder of pictures from my PC to iCloud Photos so that I can share the folder? I can put the folder on iCloud drive (the folder contains 57 pictures), but when I am in iCloud Photos on my PC, it will not let me Edit and paste, or do anything that I know to try, to get the folder of photos into iCloud Photos, Shared. Help??
