Center category image and adjust size.

When I click on the category image, it brings up a bigger image and then the products in the category. How can I:

1. Center this image
2. adjust the dimensions

Thanks

That worked. Thanks

What about if I do not want the image to appear at all?

How could this be done only on the category page?

For example I have a page with all of the category icons. When you click the icon it opens the category and that icon is at the top. I need to hide it but the css display: none hides the icons on the category list page.

Ack nevermind, temporary insanity.

.hikashop_category_description .hikashop_category_image{
display:none;
}

Where exactly does one enter the CSS code? I can only assume (likely incorrectly) that the category in question here is under the HikaShop Menu's? If so, the category is set to display the Category image, and then the product listings. Where I am trying to center the Category Image is on the page:
www.eutopiantrader.com/shop/all-knives/everyday-carry-knives
I don't see anywhere to enter any CSS and I am not sure if this is meant to be done elsewhere or not. I want the size of the category image to remain the same, just move it from Left to Center.

Cheers

Thanks Jerome, I will look into this, however, I don't have access to the CSS, so I have to work with what I have and escalate any CSS changes to my web developer. In the meantime I created a work around by adding an additional column before the others and use the "Text Block" addon to place a Customer Testimonial in that space which moved the images over perfectly.

Cheers Mate!
