When you turn on the iCloud Photos feature on your device, you can share photos and videos with an iCloud Link using your iPhone, iPad, or iPod touch, or on iCloud.com. Anyone with the link can open the photos. iCloud Links expire after 30 days.
To see all your iCloud Links, do either of the following on your iPhone, iPad, or iPod touch:
In the Photos app: Tap For You, then look in the Recently Shared section.
In the Safari app: Go to iCloud.com, open Photos, then tap iCloud Links.
Tap an iCloud Link for more details. You can view the photos and videos you share, see the expiration date, copy the link so you can share with other friends, and stop sharing before the 30 days are up.
When you share an iCloud Link, people you share with may be invited to add photos and videos that were taken around the same time and place. See the Apple Support article Use Sharing Suggestions in Photos.
iCloud Links are different from Shared Albums. To learn more about Shared Albums, see the Apple Support article Use Shared Albums in Photos.
