Add Full Background Photo to page

How do we add a full fit photo background to a page, like it looks in the slider? For example, I would like my contact page to be a full photo, with the contact form on the photo. Thank you.

Hello there,

On the pro version of Sydney, there is an easy option to set custom background image for your page.

I would unfortunately not be able to do that at this time - is there no other way, even through the page or row settings?
