Woocommerce featured products and product category images align vertically

I’m using Woocommerce version 2.0.8 with Suffusion verson 4.4.6. I also installed the Suffusion Commerce Pack plugin, which helped with all issues except for one. Love the plugin and the theme, and my client really loves the look so hope I can find an answer!

The images – resulting from the Featured Products shortcode – on the home page, as well as the images on product category pages are aligned vertically – stacked up on top of each other. The Featured Products short code should create a grid (I used the shortcode default of 4 columns).

I’ve seen a lot of posts about images/products showing vertically and trying to get them to show in a grid/table type of format, but nothing that resolves the issue.

Since the other posts involve other themes, it doesn’t seem like it is a Suffusion issue. Hope not anyway.

I would appreciate any help. thank you!!
