Auto import into Photos Library on Mac
I've set up my initial Photos Library by importing from the various folders of photos I have on my Mac. I've kept the original photos in the original locations. If I add new photos or make copies of photos in those folders, how do I get those loaded or registered in the Apple Photos Library? Is there a way to automatically sync, i.e. keep the Photos Library up to date, or do I have to re-import?
Maybe I've missed something but a wide variety of searches hasn't come up with anything.
I'm running the latest version of Ventura on a 2020 iMac.
Thanks in advance.
