Everything has to go somewhere. Are you saying that the head image with the veggies should drop below the "features" box? The drop occurs at 1000px. As the viewport narrows to less than 1000px what should the page look like? The page would look very awkward whichever image drops. What do you want the content to do as the page narrows?
This page has a significant number of problems. It triggers a horizontal scroll bar at 1560px. That's far from "mobile". That's just for starters. There are plenty of problems to work on.
@dresden_phoenix's post is funny. It didn't occur to me that maybe this is supposed to be a fixed width page (1000px). Even if fixed width, though, there are other problems that beg attention. Let us know.
