Display category inside product div

I need to display the category of the product inside the product div in product listings

This is useful because all products are showed in the same page and users needs to know the type of product (Photography, original illustration, serigraphy...). I need something like:

-Image
-Price
-Product name
-Category of the product
-Add to cart

I supose I should add some code in the "listing_img_title.php" to add the category, but how exactly?
