Not sure I understand your question, but yes you can use it to reload all tvshow artwork by using texturecache.py C tvshows (remove and recache). You will probably be prompted to allow recache all in your config file though. If you want to change from tmdb to locally stored images though, it's probably best to change content in Video->Files->TV Shows-> ... here you can remove and then re-add your tv shows using only local content. Then use texturecache.py c tvshows to recache your images. Then purge to clean up the leftover crud.

I know it does the art. But what about episode/Tv show nfo files
