An Oregon girl's senior pictures quickly went viral as soon as people noticed what was in the background.
Jillian Henry, 17, posted two outtakes from her senior photo shoot on Twitter with the caption, "love my senior pics."
The shoot took place in the Willamette River near her home in Eugene, Oregon. While taking the photos with her friend and photographer, Elena Nesbit, the two noticed something odd in the frame directly behind her -- a fully naked man walking his dog.

As soon as Twitter users spotted the man photobombing Henry, the pictures went viral, garnering nearly 25,000 retweets and 75,000 likes in less than two days.
In the second of the two photos, Henry can be seen laughing about the situation.
The teen says she was shocked by the response and by how quickly the photos spread.
"I posted it and was super excited when it got to just a few hundred favorites, and then I went swimming and was out of cell service for a couple hours and when I got back into service it was at a few thousand and just kept getting more and more," she told The Oregonian. "I never expected it to get that big."
