Header Image Banner Scroll

Hello there everyone!
Just a quick question, is there a way that you are able to make the ‘head image banner’ scrolling flat.
At the moment, I’ve set my website up so that the ‘image’ is just a non-scrolling crelly slider, and I would prefer to have the image option, but the setting that it’s on right now stretches out the image and makes it scroll funny, I’d prefer for this to be flat, like a straight image.

Also, with the image option, when I remove both the head line and the tagline text the button changes, is there a way to keep that stagnant?

Feel free to go in and change all of that if that’s possible!
