Here is the site: http://callmedutch.com . I'm trying to eliminate the whitespace above the picture and place it more on a level with the top of the navbar. I can't seem to get it any higher than what you see.

It seems that it may be your "shop_button" that is ('invisibly') taking up the space above the image. Try placing it inside your <nav></nav> instead of outside.
I.e. like this:
<a id="shop_button" href=.............../">Sell Your WatchP</a>
</nav>
instead of this:
</nav>
<a id="shop_button" href=.............../">Sell Your WatchP</a>

You may then need to make some other adjustments as well...

Yes putting it inside the NAV allows the picture to move up. I just have to figure out how to get the Shop button to display from in there. It disappears.
