Also two C-47s were damaged as well as damage to ground targets and a transport ship, lugger Helen Dawn that had run aground and was strafed and destroyed.

The picture's legend says 1943 ....
On Wikipedia it's told that the 6th Troop Carrier (now 6th Airlift) was based at Port Moresby.
There is also an interesting history about the origine of the logo The Bully Beef Express named in 1942.
I know all this don't tell you the precise location of the photo, but it can help you to find new links.
