Picasso determines orientation according to ExifInterface.ORIENTATION_*. All possible values in MediaStore.Image.ORIENTATION are: 0, 90, 180, 270 (according to: https://developer.android.com/reference/android/provider/MediaStore.Images.ImageColumns.html#ORIENTATION). The values differ, thus orientation read from MediaStore must be translated to ExifInterface.ORIENTATION_* value.
