How to bypass folders display and go straight to photos display by using android's INTENT class?

I want my app to list/display only the phone's photos ( nothing else ) so that the user could select one of them whose bitmap will then be dealt later on by my remaining code.

The problem is that the code below instead of displaying photos directly, it first displays TWO FOLDERS ( Photos and Camera ) where photos are stored/grouped and waits for selection. How to bypass folders display/selection and go straight to photos display/selection ? Here is the current code:

Intent intent = new Intent(Intent.ACTION_PICK,
        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
startActivityForResult(intent,0);
