change the background image

I cannot figure out how to change the background image on my homepage. Can someone please help? ## Deliverables for some reason I cannot find the line of code that changes the background image on the index page of my website. I would like someone to find it and show me to how to change it myself. There are a few lines of code that resemble something like - <!-- body {background-image: url([login to view URL]);} --> But anytime I change any of them, the background is not changed... I have included a jpg in the zip file that I would like used as the background image. i have also included the home page file called [login to view URL]
