One thing you can do is to look at the pictures again. If your face is not clear at all, you could claim you don't know who the driver was. Theoritically, any of your friend, or your relatives, wife or sons or daughters can drive your car. It is not your obligation to tell the court who was driving the car.
But I really doubt if it will work or not. Usually, they evaluate the pictures before they send out a ticket. That's why only about 30% of cases are issued tickets. For example, if you had a big sunglasses when you were driving, you would have not received the ticket because they could not identify the driver.
