How can I see my photos in iCloud

If you have iCloud Photo Library turned on, the photos in iCloud are the same as on your device and can be viewed in the Photos app on your device. They can also be viewed by using a computer to log in to www.icloud.com and going to the Photos app there.

If you don't hav iCloud Photo Library turned on but are using iCloud backup, be aware that there is no way to view the contents of an iCloud backup. The only thing you can do with the backup is use it to restore or set up an iOS device. iCloud: Restore or set up your iOS device from iCloud
