How to fix issues with responsive image on Narrative theme?

Hi,

I having some issues with Narrative header image. I have tried all sorts of resizing of the image but I can’t get it to sit well on desktop and mobile.

Is there a way to upload two images but hide one on desktop and one on mobile?

Or is there a way to edit the size of the image and padding displayed on mobile only?

Currently I have the section spacing set to Extra Large and middle positioning but I have tired all combinations!

Although I am not sure if that will work as we have a landing page up

Many thanks in advance!

I am also wanting to edit the padding across the mobile side of the site and the desktop. It occurs to me this could come under the same query.
