An HTML page is interpreted top to bottom. When your javascript runs (in the head) the HTML has not yet been parsed, and therefore does not exist.

Put everythng into a function

function runMeOnLoad(){
    var galleryImg = document.getElementById('image');
    var bar = document.getElementById('imgBar');
			
    galleryImg.onmouseover = function ()
    {
        bar.style.display = "block";
    };
    galleryImg.onmouseout = function ()
    {
        bar.style.display = "none";
    };
}

And execute onload

<body onload="runMeOnLoad()">
