Реализация фрагмента с картинкой

Привет, появилась проблема не могу передать изображение во фрагмент. У меня есть адаптер RecyclerView ProductAdapter, есть Фрагмент в котором собственно создается список(заголовок и картинка),есть класс Product и есть фрагмент, который будет отображать нажатую картинку.не могу понять как и откуда вытягивать определенную картинку. Думаю что из адаптера но сама картинка задается во фрагменте.

Это код самого адаптера

public class ProductAdapter extends RecyclerView.Adapter<ProductAdapter.ProductViewHolder> {

    private Context mCtx;
    private List<Product> productList;
    public ProductAdapter(Context mCtx, List<Product> productList) {
        this.mCtx = mCtx;
        this.productList = productList;
    }
    private Fragment fragment;

    @Override
    public ProductViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(mCtx);
        View view = inflater.inflate(R.layout.list_layout, null);
        return new ProductViewHolder(view);
    }
    @Override
    public void onBindViewHolder(ProductViewHolder holder, int position) {
        Product product = productList.get(position);
        holder.textViewTitle.setText(product.getTitle());
        holder.imageView.setImageDrawable(mCtx.getResources().getDrawable(product.getImage()));
    }

    @Override
    public int getItemCount() {
        return productList.size();
    }

    public class ProductViewHolder extends RecyclerView.ViewHolder {
        ImageView imageView;
        TextView textViewTitle, textViewShortDesc, textViewRating, textViewPrice;
        Button buttonImage;
        public ImageView getImageView() {
            return imageView;
        }
        public void setImageView(ImageView imageView) {
            this.imageView = imageView;
        }
        public ProductViewHolder(final View itemView) {
            super(itemView);
            textViewTitle = itemView.findViewById(R.id.textViewTitle);
            imageView = itemView.findViewById(R.id.imageView);
            buttonImage = itemView.findViewById(R.id.buttonImage);

            buttonImage.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {

                    FragmentBigPicture fragmentBigPicture = new FragmentBigPicture();
                    FragmentManager fragmentManager = ((Activity) mCtx).getFragmentManager();
                    fragmentManager.beginTransaction().replace(R.id.container, fragment)
                            .commit();

                }
            });
        }

    }
}

это код класса

public class Product {
//private int id;
private String title;
/*  private String shortdesc;
  private double rating;
  private double price;*/
private int image;
public String getTitle() {
    return title;
}
public Product(int image) {
    this.image = image;
}
public Product(String title, int image) {
    this.title = title;
    this.image = image;
}
public int getImage() {
    return image;
}}

Это код фрагмента (не обращайте внимания на реализацию создания списка, она будет осуществлена с помощью "парсинга" сайта)

    productList = new ArrayList<>();

    productList.add(
