- "When you use iCloud Photos and delete a photo or video on one device, it's also deleted on all other devices where you're signed in with the same Apple ID."

- "If you want to permanently delete your photos or videos, you can remove them from the Recently Deleted album. When you delete a photo from this album, you can't get it back."

If you were storing photos on a computer that are not in a library connected to iCloud, you can see if there is a copy there.
