哪位老大帮我注释一下这段代码？

<SCRIPT language=JavaScript>if (document.images)
var staticlogo=new Image(88,31)staticlogo.src="1.gif"var logolink="http://www.happydrips.com"var alttext="快乐点滴"var fadeintoview=1
var visibleduration=12function regenerate()
{
window.location.reload()
}
function regenerate2()
{
if (document.layers)
setTimeout("window.onresize=regenerate",400)问题1：这里是把regenerate赋值给onresize而不调用呢，还是会调用regenerate函数？
}
var fadeset=''
if (fadeintoview)
fadeset="filter:alpha(opacity=0)"
if (document.all)
document.write('<span id="logo"" style="'+fadeset+';position:absolute;top:100;width:'+staticlogo.width+';height:'+staticlogo.height+'"></span>')
function bringintoview()
{
if (logo.filters.alpha.opacity<=95)
logo.filters.alpha.opacity+=5
else
{
clearInterval(viewit)
if (visibleduration!=0)
setTimeout("logo.style.visibility='hidden'",visibleduration*1000)
}
}
function createlogo()
{
staticimage=new Layer(100)
staticimage.left=-300
staticimage.top=120
staticimage.document.write('<a href="'+logolink+'"><img src="'+staticlogo.src+'" border=0 alt="'+alttext+'"></a>')
staticimage.document.close()
staticimage.visibility="show"
regenerate2()
staticitns()
}
if (document.layers)
window.onload=createlogo;
if (document.all)
{
w=2
h=2
logo.style.left=w
logo.style.top=h
}
function logoit()
{
var w2=document.body.scrollLeft+w
var h2=document.body.scrollTop+h
logo.style.left=w2
logo.style.top=h2
}
function logoit2()
{
staticimage.left=pageXOffset+2
staticimage.top=pageYOffset+2
}
function insertimage()
{
logo.innerHTML='<a href="'+logolink+'"><img src="'+staticlogo.src+'" border=0 alt="'+alttext+'"></a>'
if (fadeintoview)
viewit=setInterval("bringintoview()",100)
else
{
if (visibleduration!=0)
setTimeout("logo.style.visibility='hidden'",visibleduration*1000)
}
}
if (document.all)
{
window.onscroll=logoit
window.onresize=new Function("window.location.reload()")问题2：这里是什么意思？直接赋值window.location.reload不行吗，为什么还要加上new Function?
window.onload=insertimage
}
function staticitns()
{
setInterval("logoit2()",90)
if (visibleduration!=0)
setTimeout("staticimage.visibility='hide'",visibleduration*1000)
}</SCRIPT>
