Blurry Image

Hello All,

I’m converting a site from an existing host to WordPress. I’m using a twenty-sixteen child theme. I’ve got the site mostly done but one thing has me stumped. The header image is smaller then the actual file when downloaded and it is blurry when rendered in a browser. Can someone take a look and let me know what I’m doing wrong.

Appreciate the help!
