How can I add a top banner background image to product pages on 7.1?

Hi there, I would like to add a background image to the top banner on my products page on SQSP 7.1 site. I can't find an obvious way to do this as the media tab that is in 7.0 is missing. Is there a way to do this with custom code or any other means that I'm missing?

Here is a screen shot to show what I mean.

Many thanks

Phil

Can you share link to product in screenshot? We can help easier

I've just figured it out. For anyone else who might like to know. Add a headline section under the header for that particular page, this will then appear as a background image behind the entire header and the height can be adjusted by adding or deleting spacers.
