I've just stumbled upon a pretty cool image slideshow crossfade technique at the top of that page, and after inspecting the source code i see where all the images are called. They are simply within a div with a class of "feature-image". There's also a header and paragraph of text nested within the div to give that translucent area with a link to each particular article.
Thanks for any starting points! I'm happy to study or follow a tutorial if someone knows where to begin.
