There’s a quick, backwoods style work-around as well…
Go to TVDB, right click on poster, ‘save image as’ then drop it on the edit window:
It’s quick and dirty, but it’ll save having to hack things most people don’t know how to hack and it’ll save the pain and suffering of changing your TV Show Libraries to TMDB - that you’ll be changing back later when you find out it’s not the miracle cure you thought it was ('cause TMDB sucks for TV Shows).
