I do not know any of the details in this particular case but...
my company uses pictures sometimes. You can buy pictures of models, items etc, from some companies. You can either buy the rights to use the picture, or buy the exclusive right. The latter is a lot more expensive, about 5 to 10 times mostly.
What sometimes happens is that other companies use the same picture or part of the picture in their advertisements, when you buy it not exclusive. This is not really a problem unless the company is in the same branche. When you look closely you see thye same pictures sometimes turn up.
I guess that is just what happened here. Both Stern and WTS bought that picture not exclusive. Not a big deal.
What is however a big deal is that that this ends my search for this hot sister-chick, realising she is not living in some american congregation....
