Hi Eugene Costello,
The Site you mentioning now is not using the Header media. It’s the Site Branding (logo on site identity) and the advertisement image on side by side and the background image is the header background image. If Header Media is set then the Header media will render on very top side of the Site.
Your previous topic was different for this. You had set/uploaded the Header Media and was render on top of the Site.
– To upload Site Logo go to ‘Appearance > Customize > Site Identity’ and set logo.
– To upload the background image and advertisement image go to ‘Appearance > Customize > Header’ and set the background image and Advertisement Image.
Thanks
