its an interesting theory, but there is no conclusive proof. The photo does not really prove anything one way or another. Damage to the West Virginia was too extensive to determine exactly what happened.
We don't even know for sure if any midget sub entered the harbour. I-16tou was found 3 miles south of Oahu. The researchers have an interesting theory that it may have been scooped up with other debris in 1944, but this is all based on very circumstancial evidence. To me it sounds too much like the "magic bullet" theory.
I don't think we will ever know for sure what happened.
