aggiungere dissolvenza a banner dinamico

[soundforgers]

salve a tutti.
ho preso uno script per la visualizzaazione di un banner dinamico a rotazione, e vorrei modificarlo inserendo un effetto di dissolvenza tra un banner e l'altro mentre cambiano...
vi posto il codice:
[cod]

<div align="center">
<script type="text/javascript">

var ultimateshow=new Array()

//ultimateshow[x]=["path to image", "OPTIONAL link for image", "OPTIONAL link target"]

ultimateshow[0]=['http://www.wiimania.net/immagini/portale/RE4.gif', 'http://www.wiimania.net/reviews-106.html', '']
ultimateshow[1]=['http://www.wiimania.net/immagini/portale/driver.gif', 'http://www.wiimania.net/reviews-105.html', '']
ultimateshow[2]=['http://www.wiimania.net/immagini/portale/Marioparty8.gif', 'http://www.wiimania.net/reviews-100.html', '']

//configure the below 3 variables to set the dimension/background color of the slideshow

var slidewidth="600px" //set to width of LARGEST image in your slideshow
var slideheight="209px" //set to height of LARGEST iamge in your slideshow
var slidecycles="continous" //number of cycles before slideshow stops (ie: "2" or "continous")
var randomorder="no" //randomize the order in which images are displayed? "yes" or "no"
var preloadimages="yes" //preload images? "yes" or "no"
var slidebgcolor='white'



//configure the below variable to determine the delay between image rotations (in miliseconds)
var slidedelay=5000

////Do not edit pass this line////////////////

var ie=document.all
var dom=document.getElementById
var curcycle=0

if (preloadimages=="yes"){
for (i=0;i<ultimateshow.length;i++){
var cacheimage=new Image()
cacheimage.src=ultimateshow[i][0]
}
}

var currentslide=0

function randomize(targetarray){
ultimateshowCopy=new Array()
var the_one
var z=0
while (z<targetarray.length){
the_one=Math.floor(Math.random()*targetarray.lengt h)
if (targetarray[the_one]!="_selected!"){
ultimateshowCopy[z]=targetarray[the_one]
targetarray[the_one]="_selected!"
z++
}
}
}

if (randomorder=="yes")
randomize(ultimateshow)
else
ultimateshowCopy=ultimateshow

function rotateimages(){
curcycle=(currentslide==0)? curcycle+1 : curcycle
ultcontainer='<center>'
if (ultimateshowCopy[currentslide][1]!="")
ultcontainer+='<a href="'+ultimateshowCopy[currentslide][1]+'" target="'+ultimateshowCopy[currentslide][2]+'">'

ultcontainer+='</a>'
ultcontainer+='</center>'
if (ie||dom)
crossrotateobj.innerHTML=ultcontainer
if (currentslide==ultimateshow.length-1) currentslide=0
else currentslide++
if (curcycle==parseInt(slidecycles) && currentslide==0)
return
setTimeout("rotateimages()",slidedelay)
}

if (ie||dom)
document.write('<div id="slidedom" style="width:'+slidewidth+';height:'+slideheight+' ; background-color:'+slidebgcolor+'"></div>')

function start_slider(){
crossrotateobj=dom? document.getElementById("slidedom") : document.all.slidedom
rotateimages()
}

if (ie||dom)
window.onload=start_slider
window.onload=runSlideshow()

</script></div>
[/cod]
qualcuno sa per caso come posso fare?
non ci sono ancora riuscito e sn un paio di giorni che ci provo... non sono ferratissimo in java

[soundforgers]

nessuno ha qualche idea??
io ho una funzione che sto provando ad includere ma non dunziona mai... vi posto il codice:

var slideShowSpeed = 3000
var j = 0

function runSlideShow(){
   if (document.all){
      document.images.sponsor.style.filter="blendTrans(duration=2)"
      document.images.sponsor.style.filter="blendTrans(duration=3)"
      document.images.sponsor.filters.blendTrans.Apply()      
   }
   if (document.all){
      document.images.sponsor.filters.blendTrans.Play()
   }
   j = j + 1
   //if (j >= (p-1)) j=0
   t = setTimeout('runSlideShow()', slideShowSpeed)
}

vi pprrrrego aiutatemi
