According to the episode guide...(and what remains of my memory..)..that's a picture of Sol K. Bright who played Makua, (the Kahuna), who put the curse on the King Kamehameha Club before the surf ski race. I believe this particular picture is from when JQH and Rick are being interviewed by the local tv station and Makua shows up and administers the actual curse. From episode 1.11 "The Curse of the King Kamehameha Club"

Hi 308 Guy,
Thank you for the information. I don't think this Sol K.Bright takes such a hot picture, with that haircut and blouse he looks exactly like a seedy Romanian Duchess
on the lam from Roger Moore in a episode from The Saint that I just saw.
