Hi Paul,
Each of our templates will include a Quickstart Package which is full website package that includes: templates, extensions, database, images … and with our QS Installation service, we will install it for you and once installing the quickstart successfully, you will have a complete website that is exactly same as our Demo (in Quickstart, we use blank image due to copyrights) except for the commercial 3rd party extensions used in each template like EasyBlog in JA Biz template. Because this extension is paid extension and you need to purchase it separately and install into your site.
Regards
