Aerial Photo Map of the US

We wanted a way to showcase all of the photos from a 50 states in 50 days campaign that we ran through our instagram. We create a page using opensource map code, and created a pop up window that would show the embedded Instagram photo or video from a state that the user selected on the map. There are a lot of images on this page, but not a lot of text, so I wanted to learn more about optimizing the metadata of the site for SEO. The current version is live at http://www.dronesdaily.tv
