NextGEN Gallery Basic is our free plugin available for download in the WordPress.org plugin repository (or through your WordPress dashboard under Plugins > Add New). It includes basic gallery displays (Slideshow, Thumbnail Gallery and Imagebrowser) and settings. Support is provided by community forums on wordpress.org.
NextGEN Gallery Pro is our premium plugin that is installed alongside NextGEN Gallery. The plugin adds premium gallery displays, pro lightbox display that includes image commenting, social sharing, and ecommerce. In addition to receiving all available updates for NextGEN Pro and *NextGEN Plus, your Pro membership also includes direct email support from us.
*NextGEN Plus includes all premium gallery displays, but does not include ecommerce.
