I need your help with categories

[mozack]

Hi,

I've my prestashop store almost done (design), but i have one problem. My categories are displayed by this way:

Master Category (no products) > Sub-Category (each one with their products)

when i click on master category, only appear his description, and nothing more inside. How can i put subcategory images to show? (just images)

Thanks
