Having trouble with full frame image

Question

I want to make my image expand with the website and different screen sizes so it's always the full background. As you'll see on large screens it doesn't expand all the way and on the iPhone it doesn't as well. I've tried everything. I've stretched the box to both sides of the page as well as both top and bottom of page so you see the red appear around the box. I thought this would work. I've changed the page height from tall to short. I just can't figure out why it won't expand. Any suggestions?
as you'll notice at the bottom. I've made the background color of the land but where the water is it doesn't expand all the way.
as you can see on the phone it's worse and doesn't expand all the way

Embed the image first:
[Embed(source="logo.gif")]
[Bindable]
public var imgCls:Class;
then assign it:
this.source = imgCls;
