This theme supports the WordPress Gallery shortcode which lets you create simple galleries like the one you see below. However, what sets this one apart from other themes that incorporates the gallery shortcode is the fact we’ve given you the ability to view gallery photos within a special viewer that also gives you the ability to navigate from picture-to-picture. You also get the option to enable photo comments.
You can, of course, use any gallery plugin you want, even using sliders within your page or post.
