I know for a while, full episodes were free on their website but that might have only been in the US. Oh, I hadn't realized he was in it as I started watching it for George Blagden who plays a monk who gets taken by the Vikings and slowly assimilated. And there are a lot of men with beards in it and really interesting hair styles.

Most of the Viking stuff I reblog comes from a Tumblr I follow that focuses on the show but also does broader Vikings' stuff. They deal a lot with aspects of how the myths would feel in sort of reality and culture clashes with the English. Since the main characters are based on famous Vikings who are in that place of being partly legend and partly truth. I highly recommend it if you can find a way to watch it.

You could do a collage of the pictures, that way you could have multiple images since the colors work well together.
