Automatic rotation

Images taken by some cameras carry the orientation property. Automatic rotation is applicable to only images that carry the orientation property. After you enable the automatic rotation feature, DCDN automatically rotates these images to a proper orientation. You can enable automatic rotation by following instructions on Enable image processing.
