要完成此效果把如下代码加入到<body>区域中
<SCRIPT language=JavaScript>
var d=0
function JM_fade(ob){
if (d==0) {ob.filters.alpha.opacity+=1} else {ob.filters.alpha.opacity-=1}
if (ob.filters.alpha.opacity==100){d=1;} else if (ob.filters.alpha.opacity==0){d=0}
}
setInterval("JM_fade(u)",10)
</SCRIPT>
<center><IMG style="FILTER: alpha(opacity=0)"
src="http://jojoo.net/www.jojoo.net/LOGO.gif" name=u>
