Does anyone know where Google pulls this image from?

It's probably a photo submitted to Google Maps for that location. The photo was probably taken by a user. I'm guessing Google probably features the most-clicked-on photo for that location in the search results.

You could try to do a reverse image search ? Download the image or paste the url to in in tineye...

What do you mean "change it"?

Do you work for this facility?

It is owned by someone named bighandking.

Google search uses Panoramio pictures in conjunction with Google Earth and Google Maps. Pictures are taken, geocoded, uploaded to Panoramio, reviewed by the Panoramio staff, and then submitted to Google.

When people do searches, use Google Maps, or Google Earth and go to a specific place, Google can display the chosen Panoramio image. I do not know how that process works, though.

I guess you could try to change it by taking your own picture and going through the process with Panoramio?

Presumably, you would have some control over this if you sign-up for Places for Business and identify yourself as responsible for the venue.

That's why I asked you if you are somehow associated with the venue.
