Product navigation - go to home

I've created a page with categories module on left and product on main content
when user click on product or categories he need also to come back , how can i do without force user to click browser back button ?
i'd like something like an "eshop Breadcrumbs"

I'd like too something like an "eshop Breadcrumbs" ...
If the product details page showed there is not any information about category.

For example:
1. showed products on category is okay:
eshoptemplates.com/fashionpro/women/dresses.html
2. When I click to product "Cotton Shirt" I do not know where I am ? There is missing information about category.
