Ok I understand now.

Ok I cut out the top of the header, then cropped the header to make room.

Uploaded both and added backgroundimage here:
Code:
#navMainWrapper,  {
    margin: 0em;
    background-color: transparent;
    background-image: url(../haskellgraphics/images/NavCat_BG.jpg)
    font-weight: bold;
    color: #ffffff;
    height: 1%;
    width: 100%;
    }
But I still got nothing.

I'm just guessing on how to edit the css honestly.
