How My Photo Stream works with iCloud Photos
My Photo Stream uploads your most recent photos (except Live Photos) so that you can view and import them to all of your devices. Photos are stored in My Photo Stream for 30 days. iCloud Photos uploads all of your photos and videos to iCloud and keeps them up to date across your devices.
