Customise Tesla theme background

Hi, I have a feeling that the answer is going to be no, but is there a way of changing the background image (NY Skyline?) on the Tesla theme? It’s a beautiful theme, but I’m thinking about using it in building a site for a UK based business so wondering if I could maybe change it to an image of Big Ben/other UK landmark. Thanks so much Pui

Got my Banner back in place. However, the size of it is huge and it is very distorted. Using a .png Tried Normalizing images but that has not solved the problem.

Any ideas?
