Answer 1

To get the image from specific file use select and select arg like this for you it will be Image in place of Audio

 String selection = MediaStore.Audio.Media.DATA + "=?";

        String[] selectionArgs = new String[]{""+file_uri};

And here file_uri is of string type just declare a string named file_uri=your file name .

So your code will be like this

 MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, selection,
        selectionArgs, orderBy + " DESC");
