Не могу вывести галерею. Использую yii2-gallery-manager

Использую yii2, yii2-gallery-manager

Создал контроллер

class GalleryImageController extends \yii\web\Controller
{
public function actions()
    {
        return [
            'galleryApi' => [
                'class' => GalleryManagerAction::className(),
                // mappings between type names and model classes (should be the same as in behaviour)
                'types' => [
                    'portfolio' => GalleryImage::className()
                ]
            ],
        ];
    }
    public function actionIndex()
    {
        $dataProvider = GalleryImage::find()->all();
        return $this->render('index', ['model' => $dataProvider[0]]);
    }
}

Папка с картинками лежит в папках web и в backend'e и в frontend'e. В БД 1 запись

1. id - 1
2. type - jpg
3. ownerid - 3
4. rank - 10
5. name - maxresdefault.jpg
