lion Of course 🙂
It's a simple CSS change, which is below
This will control the "main header" you see when you first access the site (until you dismiss it) and the sub pages header (where the background color is usually set by the tag color)
.Hero {
background: linear-gradient(rgba(0,0,0,0.75), rgba(0,0,0,0.45)),url(https://<full path to image>) !important;
background-position: center !important;
background-repeat: no-repeat !important;
background-size: cover !important;
color: #ffffff;
}
Note, that I'm using an overlay (the linear-gradient referenced above) to darken the image as it means the text is more readable. It's not essential, and if you didn't want this, you'd change the css to
.Hero {
background-image: url(https://<full path to image>) !important;
background-position: center !important;
background-repeat: no-repeat !important;
background-size: cover !important;
color: #ffffff;
}
Hope this helps.
