Galleria Galleria is a fork of <a href="https://wordpress.org/extend/plugins/photo-galleria/" rel="ugc">Photo Galleria</a> that is designed to minimize resources and selectively load javascript. This plugin will only load javascript on pages that actually have a gallery. Galleria Galleria also keeps standard gallery styling if javascript is not enabled. Beyond that, this plugin is built using the <a href="http://galleria.aino.se/" rel="nofollow ugc">Galleria javascript library</a> that allows for advanced theming and customization.

<h4>Gallery Shortcode</h4>
This plugin uses the standard [gallery] shortcode to create slideshows. It also adds support for a per gallery height attribute in the format [gallery height=500] to create a gallery with a height of 500px.
<h4>Custom Galleria Themes</h4>
The <a href="http://galleria.aino.se/" rel="nofollow ugc">Galleria javascript library</a> uses themes to style your galleries. If you would like to customize the build-in themes or use a <a href="http://galleria.aino.se/themes/" rel="nofollow ugc">paid theme</a> add a <code>galleria-themes</code> directory inside your WordPress theme directory (make sure to place your galleria theme javascript file directly within the <code>galleria-themes</code> directory.) When you visit the Galleria Galleria settings page your javascript file will appear in the design dropdown menu.
