var imgelement = document.getElementById("imglo");

imgelement.style.position = "fixed";//IE中只支援IE=>7..其他沒大麻煩
imgelement.style.left = "50%";

imgelement.marginTop = ((parseInt(imgelement.style.height,10)/2)*-1) + "px";
imgelement.marginLeft = ((parseInt(imgelement.style.width,10)/2)*-1) + "px";//IE7會死得好慘
