Thanks for writing. Sure, I can guide you 😉

First of all, when creating a page in which you want to show the gallery, you need to select the gallery template for that page.

You can read more on this link to understand how to use page templates: http://nicethemeswp.com/support/theme-docs/bbq/#page-templates

Please, be sure you select the Gallery template for that page. If you don’t set your page template with the gallery template it won’t work.

Second, you need to upload pictures to that gallery. In order to do this, use the Page mediauploader ( The “Add Media” button below the title in the page form ) choosing as many pictures as you want from your hard drive. You can edit the information for the images. Then save changes and publish the page.

Finally, the template will make the magic happen.

Best,
Juan.
