This is one of the most used modules in Cornerstone, since it is dealing with such an important part of the site - pictures. This module can display separtate images or the series if images called "galleries".
There are many presets to show your article list. But if you don't like any of those - you can always create your own by selecting the "According to template" option in the Image tab of your article list (Article list > Image position > According to template). You do need to know some html and css to do that though.
