You can achieve that using CSS,

Please add this in Customizer -> Custom -> CSS and change the image source url

.x-logobar-inner {
	background: url('your-image-url-here.jpg') no-repeat center top;
}

let us know how it works out for you.

Cheers

Another question for you. Is there a resource available that would tell me what css styles to modify for things such as this?

You can use “Firebug” extension for Firefox and Chrome Built-in function called “Inspect Element”

You can simply google those two things and it would give you thousands of result and tutorials on how to use them also and how to get the classes for specific division.

…and now have the header image I want. How do I now make it mimic the dynamic window size updating shown on the Theme X demo page? (shown here: http://theme.co/x/) When I open that web page, the Nav bar is perfectly aligned at the bottom of the window, even when I resize the window. Both the Nav bar position and header background image update dynamically to match the users window size. How do I do that? Then as I scroll down, the Nav bar goes up and attaches itself to the top of the users window. Please help and thanks in advance.

Thanks.
