iCloud photos
Can I copy photos from one iCloud account to another, if yes how?
Thanks, Vid.
There are several ways to do this.
This guide explains how you export iCloud data.
Archive or make copies of the information you store in iCloud - Apple Support
Then you can upload it on the other account after.
You can also do it by signing out from a device and keep the iCloud photos, then sign in with another account and upload the photos to that account.
If you have more questions, just ask!
Good luck!
