Apple says on the support page that going forward, users who want to make sure that their photos and videos are available across their devices and are safely stored in iCloud should start using iCloud Photos. My Photo Stream was available before iCloud Photos and has, for the most part, been replaced by it. And with My Photo Stream closing down, well, you have no choice but to move on. Funny how that happens, right?

Make sure you have iCloud Photos enabled on your device
As Apple notes, the photos and videos on My Photo Stream are already stored on one of your devices. As long as you still own the device where the originals are kept, you will not lose any photos or videos due to the My Photo Stream shutdown. But if a photo you want is not in the library on a particular iPhone, iPad, or Mac, make sure that you add it to the library on that device.
- Open Photos and tap Albums.
- Tap My Photo Stream > Select.
- Tap the photos that you want to save, then tap the Share button > Save Image.
On your Mac
- Open the Photos app, then open the My Photo Stream album.
- Select any photos you want to save that aren't currently in your photo library.
- Drag them from the My Photo Stream album to your Library.
To set up iCloud Photos, you need an iPhone running iOS 8.3 or later. On iOS 16 and later go to Settings > [Your name] > iCloud > Photos and toggle on Sync this iPhone, iPad, or iPod touch.
On devices running iOS 15, iPadOS 15, or earlier, Turn on iCloud Photos. Once you've enabled iCloud Photo all of the photos and videos in your photo app are added to iCloud. Any videos already stored in iCloud Photos are now available on your device.
To view photos and videos stored in iCloud Photos, open the photos app and tap on the Library tab on the bottom left of the screen. The photos and videos you see are stored in iCloud Photos.
