It shouldn’t.

If it makes you nervous, though, you could make a backup copy of your photo library first.

Thanks. For now I'm doing the workaround where I add photos I need now to my shared folder, and import from there... so I just want to get it working going forward, I'm sort of OK for the moment. It's clunky but familiar and working.
