hello i can change language for discripton movie ? about moviedb HOT 1 OPEN

If you want the description in a different language pass a language parameter[0]. You need to find the language code for the language you want, tmdb uses ISO 639-1 codes and can be found on wikipedia here[1].

As with the picture. A image is not sent in return, just the link to the image to reduce the size of the response. To get the image you need to append (or add) the poster_path value (in your case: /2h00HrZs89SL3tXB4nbkiM7BKHs.jpg) to the image endpoint for themoviedb.
You can read more about this on the official docs[2] it, but in summary what you need to do is add append the response to https://image.tmdb.org/t/p/w500 where w500 is the width you want. In your example it would be https://image.tmdb.org/t/p/w500/2h00HrZs89SL3tXB4nbkiM7BKHs.jpg.
Here is a list of the sizes available: https://www.themoviedb.org/talk/53c11d4ec3a3684cf4006400?language=en.

Here you want to change the value of id and language to what you want.

const moviedb = require('moviedb');

let tmdbLibrary = moviedb(apiKey);
let method = 'searchMovie';
let argument = { id: 329865, language: 'no'};

tmdbLibrary[method](argument, callback)
