Fading Image Slideshow: random help.

Hi there,

I found this script here: [url]http://www.dynamicdrive.com/dynamicindex14/fadeinslideshow.htm[/url] … it’s the closest thing to what i’m looking for: a fading slideshow script that cycles randomly. This one, however, isn’t random. I’m not too good at Javascripting, could someone tell me how I’d turn this into a random script instead of cycling please?

Thanks!

[CODE]

var slideshow_width=’140px’ //SET IMAGE WIDTH
var slideshow_height=’225px’ //SET IMAGE HEIGHT
var pause=3000 //SET PAUSE BETWEEN SLIDE (3000=3 seconds)

var fadeimages=new Array()
//SET 1) IMAGE PATHS, 2) optional link, 3), optional link target:
fadeimages[0]=[“photo1.jpg”, “”, “”] //plain image syntax
fadeimages[1]=[“photo2.jpg”, “http://www.google.com”, “”] //image with link syntax
fadeimages[2]=[“photo3.jpg”, “http://www.javascriptkit.com”, “_new”] //image with link and target syntax

////NO need to edit beyond here/////////////

var preloadedimages=new Array()
for (p=0;p<fadeimages.length;p++){
preloadedimages[p]=new Image()
preloadedimages[p].src=fadeimages[p][0]
