Want to include NextGen Gallery Slideshow within my header

Hello,

I am using the ‘SG Window’ theme for my site https://www.inspiredautosport.com. I would like to know how I can insert the Next Gen plugin slideshow within the Header. If you look at the site, the Header already shows one image and I would like to include additional images and make it a slideshow. I like how this header image shows, full width, covers the whole page.

Thank you for your help
Roger
