Can't display folderes

I have apparently painted myself iinto a corner and cannot figure out how to display my folders and am up to my ears in a project. I've attached a screenshot of where I am. Obviously I am not as up to speed on LRC as I want to be, so any help is deeply appreciated. The parent folder of my project contains 2300+ images in numerous subfolders.

Thanks to those who know more than me (which is probably a cast of thousands 🐵 )
