My thousands of photos are filed in folders on my PC and that is the way I’d like to see them in Plex - Thanks for your assistance iM
In Plex Web, your options for viewing photos are “Photos” and “Timeline.” Photos mode mimics your folder structure.
Thanks beckfield!
Your answer was spot on, making me have a second look. My ‘old age’ sometimes interferes with keen observing. Best, iM 
No problem. Welcome to Plex.
