Storing pictures on icloud but not iphone
I have a bunch of old family photos that I want to keep in cloud storage as opposed to on my PC or thumb drive. Can I store them in icloud by uploading them from my PC without all of them also getting posted to my iphone?
Also - I'm thinking about switching to a Mac very soon. Same question...can I have separate storage areas in icloud for things like old photos that you don't want on your iphone? I don't need 548 pictures of great grandma on my iphone!
Thanks!
