Upload the bitvolution-image-galleria folder to the /wp-content/plugins/ directory.
In the WordPress Dashboard, activate the plugin through the 'Plugins' menu.
In the WordPress Dashboard, go Settings->Media and modify the Thumbnail size to 80x80 (WordPress default is 150x150) and the Medium size to 500x375 (WordPress default is 300x300). If this is a brand new site with no images uploaded you can go to the next step. However, if there are already existing images uploaded, WordPress will not resize them to your new dimensions and so this plugin will not function all that well. To fix this is easy - Install the Regenerate-Thumbnails plugin and use it to re-generate all images to your new dimensions. Once done you can remove the Regenerate-Thumbnails plugin.
Upload a couple of images to a post and use the normal gallery shortcode [gallery] to display the image gallery.
Optional for a trivial increase in performance - Copy&Paste the CSS code in bitvolution-image-galleria.css to your themes style.css file and then comment out the line that contains "bitvol_galleria_css" in bitvolution-image-galleria.php.
