Update: Who's responsible for Weiner campaign flub?

When a New York City mayoral candidate's campaign website mistakes the Pittsburgh skyline for Manhattan, who's to blame?

A faceless PR firm, naturally:

A technology firm is taking the blame for the photo mix-up. NGP VAN, which does consulting work for Democratic campaigns, said in a statement that a designer simply used the wrong image.

"This is our fault," the company said. "NGP VAN acknowledges that the image of the wrong skyline on the placeholder page for the Weiner campaign was our honest mistake, and not that of the Weiner campaign."

The company said the designer got the image from a set that included NYC images, "but obviously this image was not of New York City, as the Weiner campaign had requested."

"With the image behind a strong blue background, our team did not catch this mistake. The offending image has been replaced," the company said.
