Stop with the frigging thumbnails

I’m losing my mind here. I’ve been fighting with this for ages on both version 16 and 17 of Kodi. I want my movies to have actual posters in them, not thumbnails or worse yet just blank boxes. I can’t figure out why I’m getting this? Can someone help?

Thanks, I’ve attached a screenshot of what I’m seeing.
