Showtime Plugin Navi-X

While looking at the plugin code I found this

if (service.tmdb == '1') {
var item = tmdb.getMovie(playlist.list[id].name);

if (item) {
                page.metadata.title = item.title;
                var data = showtime.JSONDecode(showtime.httpGet("http://api.themoviedb.org/3/configuration", {
                    'api_key': tmdb.key

Is this working? If so how would it work as setting up a playlist you have to add a thumbnail and description of the movie. I'm guessing the api should do this automatically?

I'm looking to see if a standalone plugin could be done to read files from my NAS.
