On my system (Xampp) the gallery pictures are display far to big. No thumbnails are created, the plugin is just displaying the full size images, only limited in size by the template.
this is the link from the page
<div class="gallery">
<a href="/joomla/images/com_edocman/galleries/Queen_Elizabeth_01.png#joomlaImage://local-images/com_edocman/galleries/Queen_Elizabeth_01.png?width=1920&height=1080" data-caption="">
<img src="/joomla/images/com_edocman/galleries/Queen_Elizabeth_01.png#joomlaImage://local-images/com_edocman/galleries//thumbs/Queen_Elizabeth_01.png?width=1920&height=1080" alt="">
</a>
where does the thumbnail gallery image get the height from? There is no thumb folder and i cant see any css for this.
