Woocomerce pages, edit them

[lukeurtnowski]

I have the site

URT URT • Perfect Clothing for Ocean Users

I’m trying to figure out how to edit a few of the shop pages,
(the category pages)
http://urturt.com/product-category/mens/
(and the product pages)
http://urturt.com/product/big-urt-navy-heather-2/
I am trying to remove the sidebar from each of the pages, and a way to increase the size of the pictures, to make up for the no-sidebar thing.

Thanks

I got rid of the sidebar!

put this in my css file from the editor in the admin panel

/*----WooCommerce-------*/
.woocommerce #main-content{width: 100%;}
.woocommerce #sidebar{display: none;}

How do I make those images use the 300 x 300 version of the images and not the 150 x 150 version instead?
