Why are the pictures not showing in my template?

Hi everybody,
I uploaded another template to the assets/templates folder. I made a new template in the manager and added 2 TV’ s to it like the install says. But I don’t see any background or pictures in the template. And I am not seeing the menu. What is wrong?
This is the url:
http://www.jomedio.nl/modx/index.php

I got it. Some files were not in the right folder.

I still frequently have this problem; I keep forgetting that the image url in a .css file is relative to the css file! So if I put the images in assets/images, it’s no good saying url(assets/images/image.jpg), since the .css file won’t be able to find the images. I’ve gotten into the habit of putting all template-specific images into an images folder in the same folder with the .css file, that way it’s always just url(images/image.jpg) and no problems.
