{# One batch of gallery items. Rendered inside the grid on the first page
   and returned bare by /media/page/<n> for infinite scroll. Each thumbnail
   links to the full-size file: the theme's lightbox opens it large with
   previous/next and slideshow; without JavaScript the link shows the picture. #}
