Gordie... the code will still work. The webpage was just an easy way to "make" the code. You can do it yourself this way:
(The code goes in the Footer)
<script type='text/javascript'>
/*
Change Any Image On Page
Created by iFusion
*/
var img_b = new Array();
img_b[img_b.length++] = ["OLD IMAGE URL" , "NEW IMAGE URL"]
var all_images = document.getElementsByTagName('IMG');
for(i=0;i<all_images.length;i++){
for(j=0;j<img_b.length;j++){
if(all_images[i].src == img_b[j][0]){
all_images[i].src = img_b[j][1];
}}}
</script>
Replace OLD IMAGE URL with the url of the image you want to replace
Replace NEW IMAGE URL with the url of the new image you want to use
Add more of these lines if you have several images to swap:
img_b[img_b.length++] = ["OLD IMAGE URL" , "NEW IMAGE URL"]
