Ok, but with the method you referenced, import does not create new files under /photos/library. They are being accessed from the external library.
Perhaps my understanding is not correct, this is seen in the unraid docker:
-v /import:ro This folder will be periodically scanned, contents will be automatically imported into Immich
Question I have is, how to use an import folder to automatically 'read' and import/add the images to the immich library, leaving the import folder intact?
