How to use photo collections in Messages
Send and receive collections of photos using the Messages app
The ability to share photos with friends and relatives is a great feature of the Messages app and it is one of its primary uses. Showing off holiday snaps, weddings, birthdays and other events with your contacts is great fun. We used to have to do it one photo at a time, but now it is possible to share whole collections of photos in one go. All you need is iOS 15 on your phone (it works in Monterey too).
A photo collection is like a stack of photos, so instead of a dozen images in a long vertical list in a Messages conversation, you see a stack of images instead. You can browse the images and save individual ones or the whole lot. It keeps the Messages conversation cleaner and simpler.
