This works well, nice, thank you !

Now I just have to have the same height as the shop page (if you want to please):

http://www.worldofpixels.be/shop/

And can you also adapt the code so I have the same on my product page belonging to that category, example on http://www.worldofpixels.be/product/1/, http://www.worldofpixels.be/product/2/, and so on ?

PS: I can also see some widgets below the product page, how can I edit this product page in general?
