I'm not sure how this could be done, if possible.
The photo for this aircraft shows as being by Doug Johnson. Today I talked on the phone with previous owner David Keith in Ocala, FL. He called me because he found my photo of this plane under its old registration and just wanted to give me the story behind it, as well as talk about airplanes (we spoke for 1). The guy will be 80 on Valentine's day!
Anyway, David is the photographer and has no idea how his photo got there. He described the event of the shot, and stated he was inside the hangar when he photographed the plane. He does remember sending the photo via e-mail to many people, but is not familiar with Doug Johnson. I did find Johnson on the net is discussions about Helio Couriers, including this very aircraft. Apparently he must have received the photo from someone David sent it to and then posted it.
The request would be somehow noting the actual photographer. David said he didn't mind the photo being there, but would like to have his name with it if possible, without having to do his own posting. I told him I would see about the possibility, so here I am.
