Using a photo to create a poster, is it possible?

Question

Photo

Hello. It is necessary to create an A4 advertising poster. There will be a photo in the background, and text on the hire, in fact, nothing complicated. The next question is, is it possible to use a photo found through Google? Am I violating the author's rights? Here, for example fotos.mtb-news.de/p/1204115
Thanks for the answers.
