"People have gone totally crazy! I've lost count of how many online newspapers and blogs that have used the image," Solheim told VG newspaper. "Perez Hilton wrote that he was laughing his butt off when he saw the picture, so you can say that it has gotten more attention than I had ever imagined."
Solheim led a team of wounded American soldiers on the expedition, with Skarsgard, known in the US for his role as a vampire in the Trueblood series, coming along as the team's celebrity.
"He was amazingly good at the skiing, and a great resource for me as a guide," Solheim said of Skarsgard. "He both supported and helped me with the soldiers, and inspired everyone."
The team, which went up against a British team featuring Prince Harry, was raising money for Walking with the Wounded, a charity which helps wounded soldiers recover.
