I believe that who ever takes the picture retains the right to the picture. This is why I always ask for permission to use a picture. When I was writing the Gas Pump ID book, I receivd a picture of a Wayne pump that I didn't have. I could not use it in the book because the owner would not give me permission. I even ask permission to take a picture of items that are for sale at swap meets, I feel the seller deserves this.
There was a picture of a twin American pump in an old issue of CTO that I couldn't use because I could not get ahold of the owner.
If anyone has a problem with the use of a picture I'm sure the Copywrite laws are posted on the web somewhere.
