_WHAT_ on "[Plugin: WooCommerce - excelling eCommerce] Change the look of categories page"

I have a page setup where I use the short code to show the different Categories I have.

The images are prette big and the page not easy to use.

How would I change the image size and make it like 3 Categories pr row.
