ImageViewTouch does not display image on DialogFragment

I discovered ImageViewTouch since I wanted to create image preview scaling in my application, although I need to display this image on one of my DialogFragment. But it works fine on a regular FragmentActivity, which is MainActivity, but not in my DialogImage, and I'm not sure why.

I imported the library using gradle and here is my code:

Mainactivity

import it.sephiroth.android.library.imagezoom.ImageViewTouch;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Button;

    public class MainActivity extends FragmentActivity {

        ImageViewTouch mImage;

        @Override
        protected void onCreate( Bundle savedInstanceState ) {
            super.onCreate( savedInstanceState );
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            setContentView( R.layout.fragment_main );
             mImage = (ImageViewTouch) findViewById( R.id.image );

            ImageDownloader2 imgDownload = new ImageDownloader2();
            imgDownload.download("MY_URL", mImage);

            Button click = (Button)findViewById(R.id.button);
            click.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View view) {
                    showPromoImage();
                }
            });
        }

        private void showPromoImage(){
            DialogImage promo_details = new DialogImage();
            promo_details.show(getFragmentManager(), "promo_details");
        }
    }

Dialog window

import android.app.DialogFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import it.sephiroth.android.library.imagezoom.ImageViewTouch;

/**

public class DialogImage extends DialogFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.dialog_image, container);
        getDialog().setTitle("Test");
        getDialog().setCanceledOnTouchOutside(true);

        ImageViewTouch promo = (ImageViewTouch) view.findViewById(R.id.image);
        ImageDownloader2 imgDownload = new ImageDownloader2();
        imgDownload.download("MY_URL", promo);

        return view;

    }
}

ImageDownloader2 is just a library that loads an image from a URL and then converts it into a bitmap image. I just made some settings for working with ImageViewTouch.

UPDATE:

, Activity Intent, DialogImage android:theme="@android:style/Theme.DeviceDefault.Dialog". , .
