This is probably very simple, but thanks for any help.

I have a javascript which creates a random image in a web page. If I want to set up another array in the head content which will target a separate holder script in the body how do I differentiate them. Not sure if I'm explaining this well.

Thanks again

No, that wasn't very clear at all, but I think I might get what you're saying anyway... Just give the array a different name, and that should solve your problem I think. But if you really want help you should probably either post your code or a link to it or something....

Thanks for the responses and I;ll try to see if the posted script can work better for me. I am posting the script. I have this script in the head

<SCRIPT language=JavaScript>
var theImages = new Array()
theImages[0] = '1.gif'
theImages[1] = '2.gif'
theImages[2] = '3.gif'
var j = 0
var p = theImages.length;
var preBuffer = new Array()
for (i = 0; i < p; i++){
preBuffer[i] = new Image()
preBuffer[i].src = theImages[i]
}
var whichImage = Math.round(Math.random()*(p-1));
function showImage(){
document.write('<img src="'+theImages[whichImage]+'">');
}
</SCRIPT>

And this in the body.

<SCRIPT language=JavaScript>
showImage();
</SCRIPT>

I want to set up a seperate array of images in the head which would populate a seperate area of the page. So I would have multiple random image areas on the page. I don't know how to distinguish them so that 2 scripts in the head will populate 2 seperate regions on the page with random images. Thanks for patience and help.
