Random Order of Images

[Adnan959]

Hello People,

This is the script I'm attempting to use:
http://www.dynamicdrive.com/dynamici...nslideshow.htm

This is the script for the most part - it even says there is an option to randomize the images. But I can't seem to figure out how to activate it.

//Oct 6th, 09' (v2.1): Adds option to randomize display order of images, via new option displaymode.randomize
//May 24th, 10' (v2.4): Adds new "peakaboo" option to "descreveal" setting. oninit and onslide event handlers added.

var fadeSlideShow_descpanel={
	controls: [['images/x.png',7,7], ['images/restore.png',10,11], ['images/loading.gif',54,55]], //full URL and dimensions of close, restore, and loading images
	fontStyle: 'normal 11px Verdana', //font style for text descriptions
	slidespeed: 200 //speed of description panel animation (in millisec)
}

//No need to edit beyond here...

jQuery.noConflict()

function fadeSlideShow(settingarg){
	this.setting=settingarg
	settingarg=null

Thanks in advance for any assistance.

Sorry for double posting. I had to chop out some of the script from the bottom. But its available on the link I posted.

Thanks

I think if you look in the head section for this code

displaymode: {type:'auto', pause:2500, cycles:0, wraparound:false},

and change it to this

displaymode: {type:'auto', pause:3000, cycles:3, wraparound:true, randomize:true},

hope this helps

Thanks Benq! That did work You're a star!
