Products list with images at different sizes

Hello!

I’m a photographer and want sell my prints. All my photos are different sizes, made with various types of cameras. So their not even proportional.
In my online shop (which is based on WordPress v4.2.3 and Woocommerce v2.3.13) the list of products should have images with different heights but with the same width. And the products should be listed in 3 columns like this: https://s15.postimg.org/d3nyacgcr/screencapture_1437816093339.png

How can I customize Woocommerce for such a list of products dsiplay?

Also as it shown in the image, I want for every product just the photo, with no price under the product image, the name of the product should be on the image on rollover in the center of the image. How can I do that?

Thank you in advance!
