I'm trying to follow the doc to build image urls but it keeps giving me 401 Unauthorized in the console log. Can someone shed a light here please.

I asked on stackoverflow as well http://stackoverflow.com/questions/33660742/apiary-api-movie-db-angular?noredirect=1#comment55096449_33660742

                 var params = {
                  id: id,
                  key: 'xx'
             }

        return $http({
            method: 'GET',
            url: 'https://api.themoviedb.org/3/movie/' + params.id + '/images/api_key='+params.key,
        });
