Including a Theme Header Image
To include a header image in your theme, include a div tag in your HTML with the class name "wsite-header".
If you include this <div> tag in your HTML, you can specify a theme header image in the CSS with a background property. The image location should be referenced with banner-tall.jpg
For example, a header image CSS rule will look similar to this:
The image file should be uploaded to the “Files” section of the Theme Editor. In this case file name would be banner-tall and it is a .jpg file.
Note: You will have the option to change the default theme header image using the website editor, while editing each page.
