photos in a book: censorship or something else?

[knittinganddeath]

We have a Norwegian translation of H.P. Willmott's book First World War, first published by Dorling Kindersley in 2003. Of all the photos of dead soldiers in the book, the bulk of them show Germans. There are a handful (maybe 5 total) that show Russians and Italians, as well as one Frenchman. There are no photos of dead British or Commonwealth troops. Is there any reason for this omission -- e.g. don't want to traumatize family members, lack of such photos in general, desire to create a particular narrative around the war, etc. -- or is it just a coincidence?

 

In case it's relevant, this edition of the book was apparently adapted for the Norwegian market but doesn't specify what those changes were.
