No header image on pages?

Hi,

I’m being dumb I’m sure!

I have all my content etc added, my home page has the slider set up (only using one image for the moment) but the rest of my pages have no header image at all.

I’ve read online (https://wpexplorer-themes.com/total/docs/page-header-backgrounds/) about adding the page header image but I can’t find this section – is this out of date?

Currently my pages have the logo top left, the menu top right and then it goes right into page content – no header image at all.

Can anyone advise? The temp site is http://2d3.406.myftpupload.com/ (still a work in progress though, quite a bit still missing).

Thanks in advance for any tips!

KM
