RokGallery has a non-destructive slice editor, meaning the original uploaded image is never modified, only new slices are created, each to a custom zoom and/or crop.
Load any gallery via a RokGallery menu item, with an extensive set of page configuration options, loaded from the Galleries settings. Configure the default options.
RokGallery also appears as a widget, allowing galleries to be displayed across your site. There are several layouts available: Slideshow, Showcase, Showcase Responsive & Grid.
