Step 1 Enable iCloud Photo Sharing
Follow these steps to enable iCloud Photo Sharing: Settings > iCloud > Photos > iCloud Photo Sharing.
Step 2 Share iPhone pics
Open "Photos" and choose the images you'd like to share. Tap on the arrow icon in the lower-left corner and then select "iCloud Photo Sharing". You can add your comments on this photo. Invite the members of the shared album by selecting their iCloud accounts from Contacts. Remember, you can invite at most 100 persons. By clicking the "Post" button, the sharing is done!
1. The shared album offers a permanent storage for the maximum 5000 photos and videos; therefore you have to delete some items if necessary.
2. With this service, you can also share pictures with those who do not have iOS devices by turning on the "Public Website" and the shared album can be viewed on the website.
