Can I set a header pic to my pages

Another quick q, can I set the theme to put a header pic on each page I have created, since, at the moment, there’s no header appearing other than in the front page?

I can’t see an option, and I realise that if I add a graphic to the ‘top’ of the page, the page heading will appear above it, so that’s not really a tidy solution.

Is there a way to do this?

Thx
