O'Hare UFO Photos Help

Does anyone know if these images are genuine photos from the O'Hare UFO incident from last year.

Here's the link to the blog post which has a few photos of a craft over an airport, the post is talking about the recent National Press Club, UFO conference.

I feel I've seen the photos before, but it has been hard to track them down to a source that talks more about them, probably photoshoped or something.
