Recently, a client needed to showcase a few products so I added these plugins to their site and was very happy with the results. FooGallery is a nice responsive layout that has enough configuration options to get the presentation you want without spending too much time turning every knob or pressing every switch.
FooBox Image Lightbox complements FooGallery with zero configuration. Just install and activate this plugin and you are on your way. This plugin also works with other WordPress galleries.
