There are some images that are protected from "commercial exploitation", although they are not restricted in commercial editorial use such as Wikipedia, newspapers, magazines and books on the subject.
A current case are Norwegian sculptures. Norwegian copyright law says: ยง 24. [..] Works of art and photographic works may also be depicted when they are permanently located in or near a public place or thoroughfare. However, this shall not apply when the work is clearly the main motif and the reproduction is exploited commercially.
If I undestand it correctly, such images are for example protected from being: postcards , sold separately and used in advertisement.
What is the view of the Wikimedia foundation about such images?
