Hi,
If you can save the images locally it would be better for you to load the images from your x-cart rather than 'hot linking'.
To place them below the help box, follow the instructions as per my previous message, but look for '{ include file="help.tpl" }' and copy and paste my code below that.
If you need to add the html, it can be pasted directly into [skin1]/customer/home.tpl
If javascript is involved you will need to place it in between the following tags
and
hope this helps
