Synology NAS not seeing folders

I have several pictures in my “home” folder on my Synology NAS. When I navigate to my pictures folder is says there is nothing to index. What am I doing wrong? Some folders I select will show subfolders while other will not including my “pictures” folder. I’m new to using Plex for photos and was really hoping to use Plex for slideshows of family pictures.

you could check the Synology DSM permissions for that folder… if the plex user doesn’t have access, it won’t show your content.
