Show your photos in a full immersive gallery.
It’s possible also to define a custom CSS in your template folder to customize completely the gallery.
See the plugin in action here: http://micz.it/wordpress-plugin-art-gallery/example-gallery/
<h3>Using a custom CSS file</h3>
You can customize the look of the gallery using a custom CSS file. The file must be named wp-art-gallery.css and copied in a wp-art-gallery folder under your theme root folder, the same where is stored the theme style.css file. 
This custom file will be loaded after the standard plugin css file, so you can modify only the elements you need, the other elements will be displayed as usual. You can check the standard wp-art-gallery.css to see which css elements the gallery is composed of.
<h3>Plugin source files</h3>

WP Art Gallery

A full immersive gallery. No thumbnails, no distractions. Only one image a time. Fullscreen!

Art Store allows artists to sell their work on their own WordPress website using PayPal (or any other third-party payment processor). A horizontal-scrolling gallery with each artwork can be used via a shortcode.
Using the Gallery
The included gallery uses a jQuery library called <a href="http://smoothdivscroll.com/" rel="nofollow ugc">SmoothDivScroll</a> by Thomas Kahn. You can use this gallery, or not, to display your art pieces. To use the gallery, we’ve included a shortcode. By default, the shortcode will display all your art.
<pre><code>[art-store-gallery]
</code></pre>
You can limit the number of items that appear by adding a <code>posts</code> parameter to the shortcode:
<pre><code>[art-store-gallery posts=10]
</code></pre>
You can specify a height or width to attempt to make all your images uniform. You can specify a height, a width, or both, and the gallery will attempt to use your values whilst not altering the aspect ratio of the thumbnail image.
<pre><code>[art-store-gallery height=500] - gallery with height/width set to 500
[art-store-gallery width=500] - gallery with height/width set to 500
[art-store-gallery height=250 width=300] - gallery with height set to 250 and width set to 300
</code></pre>
(Note: The gallery will use whatever crop settings you have specified on the thumbnail in the media library — you can change the crop settings by editing the image in the media library.)
