How do you get the image to be at the very top of the page ?

and then move the nav to overlap image (to the right as to not overlap the credit)

Find the section in the css box on your page for the "menu"

Make sure it includes this:

margin-top: 0px;

margin-left: 100px;

And you'll have to play around with the numbers where I used 0 and 100 as space fillers here. Might have to used negative numbers sometimes depending on where you're trying to put it.
