Help! WW I Aircraft ID

The man standing next to the airplane (photo, right) is my paternal grandfather, Dominic Naretto, who was an aircraft mechanic in the Italian Air Force during WW I. Can one of your aviation history experts tell me what type of aircraft that is in the picture? I would also appreciate any information regarding my dear old grandfather. He inspired me to study aeronautical engineering and to earn my private pilot’s license. Thank you for anything you may uncover. How about it? Any sharp-eyed readers out there recognize the airplane?—BD
