How many photos and videos can I store in my iCloud Photo Library?
The number of photos and videos you can store depends on your available iCloud storage. When you sign up for iCloud, you automatically get 5 GB of free storage, and several iCloud storage plans are available from 20 GB for $0.99 up to 1 TB.
The new app lets you organize your photos by time or location, and breaks everything into tabs labeled Photos, Shared, Albums and Projects. Apple also added new photo-editing tools as well. Notably, you can create your own digital photo books or purchase printed copies of your pictures.
