Excluding an image from a random list

Javascript Randoms....

Here is my Code:

<script language="JavaScript" type="text/javascript">
n=3;// number of all gifs
g=1;//number of random gifs

//no need to modify bellow
var theImages = new Array() //array of gifs
for(var i=0;i<n;i++){
//randomize function
function rand(){
r = Math.floor(Math.random()*n);
return r;
function showImages(){
var rr = new Array()//array of radom numbers
for(var j=0;j<g;j++){
for(var k=0;k<rr.length;k++){//check whether new random number reapets a former one or not
var j=j-1;break
else{rr[j]=r;}//if not, create new array's element
document.getElementById('g'+j).setAttribute('src',theImages[rr[j]]);//set new image
// -->

<a href="#" onclick="showImages();return false">
<IMG SRC="00.gif" ID="g0" ALT="Click to View Your Fortune" BORDER="0"></A>

What I am trying to figure out is how to EXCLUDE the origenal image (00.gif) from being one of the random selections. When the main image is clicked I want it to show a picture from a random list. However I don't want the main image to be in that list. Any comments/suggestions are greatly apreciated. Thanks.

Um, quick guess:

for(var i=1;i<n;i++){

ought to do it. If it doesn't, you probably want to post this in the Javascript forum [webmasterworld.com] here. :)
