Rettelse af slideshow script

Hejsa..

Jeg har dette script. på min hjemmeside.
Men jeg vil gerne, at den i stedet for at lave et random på transition type, skal lave en pæn fade istedet.
(en fade som denne : http://www.dynamicdrive.com/dynamicindex14/fadeinslideshow.htm)

det kan selvfølgelig også være at andre af jeg har et bedre script til formålet.. (det skal være et slideshow med manuel styring)

jeg har fundet scriptet på dynamicdrive.com
---------------------------------------------------

<script type="text/javascript">

var photos=new Array()
var photoslink=new Array()
var which=0

//define images. You can have as many as you want:
photos[0]="1.jpg"
photos[1]="2.jpg"
photos[2]="3.jpg"
photos[3]="4.jpg"

//Specify whether images should be linked or not (1=linked)
var linkornot=0

//Set corresponding URLs for above images. Define ONLY if variable linkornot equals "1"
photoslink[0]=""
photoslink[1]=""
photoslink[2]=""

//do NOT edit pass this line

var preloadedimages=new Array()
for (i=0;i<photos.length;i++){
preloadedimages[i]=new Image()
preloadedimages[i].src=photos[i]
}


function applyeffect(){
if (document.all && photoslider.filters){
photoslider.filters.revealTrans.Transition=Math.floor(Math.random()*23)
photoslider.filters.revealTrans.stop()
photoslider.filters.revealTrans.apply()
}
}

function playeffect(){
if (document.all && photoslider.filters)
photoslider.filters.revealTrans.play()
}

function keeptrack(){
window.status="Image "+(which+1)+" of "+photos.length
}

function backward(){
if (which>0){
which--
applyeffect()
document.images.photoslider.src=photos[which]
playeffect()
keeptrack()
}
}

function forward(){
if (which<photos.length-1){
which++
applyeffect()
document.images.photoslider.src=photos[which]
playeffect()
keeptrack()
}
}

function transport(){
window.location=photoslink[which]
}
