Aha!
Wikipedia got me!
Their page about Bastia - Poretta has that aerial photo, but they clearly labeled it as Bastia - Borgo. DOH!

A bit more research reveals that there were several airfields at that location.
I'll try again calling it Bastia - Borgo
Photo looking south taken in early 1944, with in the foreground a Lightning P38. The first airfield is Borgo, the second large airfield is Poretta (todays Bastia Poretta airport). Two more can be seen in the distance. Between the two nearest, a very small runway can be seen, which is the one created by the French and used by the Germans. This little track was used for Piper Cubs. US Groups based at Borgo were 52FG operating Spitfires, 111FG operating P-51 Mustangs and 415NFS operating Beaufighters.
