HOWTO | move to i cloud photo library
1 Upload from iOS
Using your iOS device, take a photo. Next, connect your device to a Wi-Fi network. That’s it – your device will upload the photo you took to iCloud. You can confirm this is done in Settings > iCloud > Photos, which shows a count of how many uploads are pending.
2 Upload burst photos
All shots in a burst photo (where, on a recent iOS device, you hold down the shutter release to take several photos and then let iOS pick the best) are uploaded by default. To save space in iCloud, turn off Upload Burst Photos so only shots marked as favourites are uploaded.
3 With other cameras
If you use another type of camera, don’t worry – pictures you import to your Mac’s photo library will be uploaded to the online one, too. After importing, open Photos’ preferences and click iCloud if you want to monitor the progress of the upload, or if you want to postpone it.
