Figured I'd ask here as thought self-hosters would care most about looking after their photos.

What do you do with friends' photos you'd like to keep hold of? Maybe there's a pic on a chat app or they've sent you a link to an album on google photos.

Would you just throw into your own pile of photos or do you carefully adjust metadata to indicate who took them? Just use dirs to separate them from your own? Interested in any and all thoughts.
