Hi all I've been tasked with uploading 15,000 of my dad's photos to iCloud Photos and I'm trying to find the best way to do this. The photos are all stored in different folders based on date, location, event, etc. I know I can upload photos using the iCloud website but I would have to select each folder containing photos one after another and this would take a lifetime to do, so that option isn't really feasible. The other option I have thought of is to create a new user account on my MBP, login to my dad's Apple ID on that account, add all of the photos to the Photos app on my Mac and let it sync them that way. That way I should be able to add all of the photos in one go. I would then delete the account again once all of the photos had been uploaded. Can anyone think of any issues with my second option, or an even better way of syncing this large volume of photos? Many thanks M.
