There are now special product codes that can be used to show an image and a description at the top of each category. These are added in the same way as normal products but less information is required.
If your product code starts with CATHEAD- then that "product" describes the category. Its image and long description will appear at the top of the category it is in.
For example, a "product" called CATHEAD-WIDGETS in the "Widgets" category would have its long description shown at the top of the Widgets category and would not be a real product.
