Header/Branding Area

I am confused about terminology. The Area at the very top of the website that carries the Website’s name and slogan and logo; is that the header?

What is the name of the area below the menu bar that has the picture of the church interior? I removed the header image thinking that I could replace the existing “header at the top” with a new one. But, when I removed it, the picture of the church interior disappeared.

What I am trying to do is slightly enlarge and move the logo to the right side of the top header/what ever it’s called. Help with these issues would be appreciated.
