Category images and text

I have installed the ecommerce modules and each product I have has been tagged using the taxonomy module in which I have set up sort of the tree structure of the webstore. I also have this tree structure in the menu so that I can click through the menu to find a product. This is all working, the problem though is that my tree is quite deep and I cannot make it with less levels. This is an example of a path through the tree from which you can see it is 4 levels deep to get to a product.

 + Webstore
     + Printing
          + Flyers
               + 200 gr paper
                    + Product one
                    + Product 2

Now, I personally don't care how deep the tree is, but what bugs me is that when I click on a category which eventually leads to a product I get an empty page (and the menu folds open at the clicked point). So I get four pages one after another which say nothing.

I am able to get drupal to display the categories children so I avoid getting the empty pages, but this doesn't look really nice.

My question

I would like to be able to give these categories an image to display which I can set per category. Perhaps also some text per category

Like said before, these categories are the "term"'s from the taxonomy

Thanks for any advice on how to procede.
