UPDATED: A Missoula photographer said the Republican National Committee used one of her photos without her permission in an election mailing attacking Democrat candidate Rob Quist.

The ad, which includes the tagline “For Montana Conservatives, Liberal Rob Quist Can’t Hit the Right Note,” arrived Tuesday at the home of one of Erika Peterman’s friends.

The friend recognized the photo, which shows the back of Quist's head with his trademark cowboy hat, as one Peterman had shown him after taking pictures at the Montana Democratic Party’s annual Mansfield Metcalf Celebration in March.

“I’m positive it’s mine,” said Peterman, who said she was invited by the Democrats to take photos at the event.

Peterman said she sent several of the photos to the Montana Democratic Party, saying she gave the party her permission to use them. She said while she posted some of the photos on her personal social media pages, the one taken from behind Quist that was used in the RNC mailing wasn’t among them.

“I don’t know where they got it from,” she said.

The flier used three photos of Quist, including one in which House Majority Leader Nancy Pelosi was added so that it appeared she was performing with Quist.
