The element that your linked image is inside has a z-index of -10 putting it behind everything on the page. If you remove the z-index reference the link works fine. It just means you will need arrange the other elements correctly - add a positive z-index or position relative to your nav and to the left sidebar.
#pageImage {
margin: 0px;
padding: 0px;
width: 1020px;
position: relative;
z-index: -10;
height: 300px;
background-image: url(../images/page_steakSalmon.jpg);
background-repeat: no-repeat;
background-position: center center;
}
