I'm really stuck on this one.

I am trying to put my logo at the top of my zen cart page. I have followed the instructions to letter (as far as I can see) and no logo appears on my site. I am attempting to do this by setting up a custom template called Elly.

I also tried to install a couple of the open source templates - Bluecart, Ocean and FutureZen, but none of them make any difference to the layout of the page. I don't understand it at all. I have been into Admin and selected the template and done the second step updating step.

My site: www.ellybooks.co.uk/shop

I would be grateful for the wisdom of those here.
