Change the default image in the blog (at `/post/)

It's a salt shaker image now. What should we change it to? @frickealissa maybe another cityscape image? Got one of Evansville? 😄

Pick one out and I'll change it in the code.

I'm working on some non-city scape images for a future step. @pmotch sending you a photo via Slack now.

I see this image is already being used at https://openvoicenetwork.org/sponsoring_member/, do we still want to put it in /post/?
