Home page - Full screen images behind header

Site URL: https://www.hotwireextensions.com/home

Hi,

I would like to make the slideshow images on my home page fill the screen and go behind the header... I have tried searching the forum but cant find a way to do this on Squarespace 7.1. Any help would be hugely appreciated!
