Hello Richter, sorry but I can't help you in any way, but maybe you can find something useful looking on this page:
this is the official website for the magazine, good research
edit: considering that you need this picture for your work, and that you won't sell this pictures (in the sense that you put them for free on your website, without asking money to nobody to see them) maybe you can ask the magazine for an explicit authorization, or not? In this case, click on this link
you'll find all the contacts you need!
