TV Show Banners/Posters showing up

I’m trying out OSMC on the raspberry pi and getting used to it to and making sure everything is running as expected before switching over all my Pi’s from raspbmc. I noticed in all my TV show directories, a banner.jpg, fanart.jpg, poster.jpg and season-all-poster.jpg file showed up in the root directory. This wasn’t the case with raspbmc, and I feel like it grabbed that image data from somewhere else besides the root directory.

I have a script that checks to see if a tv show folder is empty and automatically delete it, but these files are messing that up. Is there any way to get it to go back to pulling that data from somewhere besides the TV show directory?
