        Glide.with(this).load(content).into(imageView);
        imageView.setOnPhotoTapListener(new PhotoViewAttacher.OnPhotoTapListener() {
            @Override
            public void onPhotoTap(View view, float x, float y) {
                ActivityCompat.finishAfterTransition(OtherActivity.this);
            }
        });
