This plugin provides an automated way to convert any standard WordPress gallery that is embedded on a page using the [gallery] shortcode into a WunderSlider.
WunderSlider Gallery also supports <a href="https://wordpress.org/extend/plugins/nextgen-gallery/" rel="ugc">NextGEN Gallery</a> to embed any gallery as a WunderSlider using the [wunderslider_nggallery] shortcode or by enabling it as the default renderer for the [nggallery] shortcode.
The plugin requires the WunderSlider which is available freely for personal use and can be downloaded on the <a href="http://www.itthinx.com/wunderslider/" rel="nofollow ugc">WunderSlider</a> page.
A license is required to be purchased for commercial use, see the WunderSlider page for more details.

Usage / Notes on settings
After you have followed the instructions on installing WunderSlider and the WunderSlider Gallery plugin, go to Appearance > WunderSlider Gallery and have a look at the default settings.
<pre><code> [gallery] shortcode attributes :
</code></pre>
<ul>
<li>
The <code>size</code> attribute uses <code>full</code> by default. Set it to another size if you don’t need the full image size.
Default sizes are <code>thumbnail</code>, <code>medium</code>, <code>large</code> and <code>full</code>.
</li>
<li>
WunderSlider attributes that use a dash in the attribute name must be used with an underscore instead when passed to the <code>[gallery]</code> shortcode. If used, <code>container-class</code>, <code>container-style</code>, <code>container-height</code> and <code>container-width</code> must be passed as <code>container_class</code>, <code>container_style</code>, <code>container_height</code> and <code>container_width</code> to the <code>[gallery]</code> shortcode. 
This is especially important when the <code>display="proportional"</code> setting is used, as you will have to provide the container width and height explicitly.
Example:
[gallery display=”proportional” container_width=”80%” container_height=”360px”]
</li>
<li>
If you do not want the WunderSlider applied to a specific gallery, you must add the <code>wunderslider="false"</code> attribute, for example:
[gallery wunderslider=”false”]
</li>
</ul>
Usage with <a href="https://wordpress.org/extend/plugins/nextgen-gallery/" rel="ugc">NextGEN Gallery</a>
Any NextGEN gallery can be rendered as a WunderSlider using the <code>[wunderslider_nggallery]</code> shortcode or by enabling defaults for NextGEN Gallery shortcodes in the Appearance > WunderSlider Gallery settings.
Example:
<pre><code> [wunderslider_nggallery id="123"] will render a WunderSlider for the NextGEN gallery with id 123.
</code></pre>
The [nggallery] shortcode can be rendered as a WunderSlider by either enabling it by default or by specifying:
<pre><code>[nggallery id="123" wunderslider="true"]
</code></pre>
For this to take effect, the option to handle NextGEN Gallery shortcodes must be enabled on the settings page Appearance > WunderSlider Gallery.
As with the <code>[gallery]</code> shortcode, any WunderSlider attributes can be passed to <code>[wunderslider_nggallery]</code> or <code>[nggallery]</code> – those that use a dash in the attribute name must be used with an underscore instead: <code>container-class</code>, <code>container-style</code>, <code>container-height</code> and <code>container-width</code> must be passed as <code>container_class</code>, <code>container_style</code>, <code>container_height</code> and <code>container_width</code>.
Examples:
<ul>
<li><code>[wunderslider_nggallery id="1" container_width="80%" container_height="300px" display="proportional"]</code></li>
<li><code>[nggallery id="1" wunderslider="true" container_width="80%" container_height="300px" display="proportional"]</code></li>
</ul>
