Random image and table color on the welcome screen?

[SheilaAlighieri]

Hi!

While I was surfing the web I ran into quite an interesting website, namely of Compagnie Financière Richemont S.A. (

http://www.richemont.com/).

The pictures on the welcome page change with each viewing. So does the color of the center table. I know there is some php involved. But I am not sure how it's done exactly. Check this script:

<script type=&quot;text/javascript&quot;>
var myimages=new Array()

function preloadimages(){
for (i=0;i<preloadimages.arguments.length;i++){
myimages=new Image()
myimages.src=preloadimages.arguments
}
}

preloadimages(&quot;../images/home/copyright_2002_richemont_home<? echo $iRandom ?>_thebrands_on.gif&quot;,&quot;../images/home/copyright_2002_richemont_home<?echo $iRandom?>_investorinfo_on.gif&quot;,&quot;../images/home/copyright_2002_richemont_home<?echo $iRandom?>_companyprofile_on.gif&quot;,&quot;../images/home/copyright_2002_richemont_home<?echo $iRandom?>_careers_on.gif&quot;,&quot;../images/home/copyright_2002_richemont_home<?echo $iRandom?>_contact_on.gif&quot;,&quot;../images/copyright_2002_richemont_arrow_on.gif&quot

function goUrl(Selected) {
var newURL = Selected.options[Selected.selectedIndex].value ;
if (newURL!=&quot; &quot {
document.location.href = newURL;
}
}
</script>

These codes should do it. But I don't know how to come to the side server scripting, which randomly picks certain images and which changes the tablecolor accordingly. Check the

http://www.richemont.com

site to see what I mean.

I would greatly appreciate all help I want to use to such a script for a non-commercial website.

load the images into an array and use the array_rand function

Sheila,

What they are doing here is using naming with a random integer number.
Their images are named 1_thebrands.gif etc. where the first number marks all images belonging to one set. The color change is inherent in the images, there's nothing to do.

So you need:
n sets of images named n_imagename.gif (or jpg, any format).
A function that productes the random number between 1 and n. The just print the number as they do in the example and you are all set.

THanks guys I am sure I can work it out from here. If I run into trouble later on, I will get back to you (if I may )
