Show more than 3 thumbs under main product image?

[-Buggi-]

Hi

I have a problem with how to Show more than 3 thumbs under main product image?

I have 6-7 images to each product, and I would like to display at least 4-5 thumbs under the main image (in one line), and be able to use the slider to view the rest.
As I see it, there are plenty of space to show more images, and I have tried to mod the Product.css file, to increase the "thump-slider" frame, but I can´t get it working

I am running 1.6.1.6 with stock theme (default-bootstrap)

 

You can see in the attached picture, that there are plenty of room to show more thumbs.

 

Any input is much appreciated
