Perhaps you could update the text of that help page as its misleading.
"If you want to explore the things you can change, you can pick the URL from the ADD TO CART and open it in a browser window. You can view source to see various elements of the cart and some of them will have IDs, you can modify them by placing jQuery statements inside the EJEJC_shown function as shown above."
The header graphic has an id of imgHeader - this doesn't seem to work so perhaps list only those that can be changed:
<script language="javascript" type="text/javascript">
<!--
function EJEJC_shown() { jQuery("#imgHeader").attr("src", "http://www.removed for privacy.com.au/images/mix/ejunkie-Cart-Img.gif"); }
// -->
</script>
I'd like to have a crack at cracking the layout for the header graphic but how can I do that without the source code - given that sits on your server?
Sounds a bit too hard for my programming skills.
Anyway, thanks and all the best.
p.s. Lemonbar, please advise if you ever get it happening as I'd love to know how to do it.
