A shortcode which shows an gallery of downloadable images. The basic idea was to have an easy way to make some images available for download. 
For a working demo see: http://plugins.funsite.eu/downloadable-gallerie/
<h4>shortcode</h4>
<pre><code>[downloadable_images taxonomy="gallery" slug="wallpaper"]
</code></pre>
The default for taxonomy is gallery, the default slug is “wallpaper”. So the above could also be used as
<pre><code>[downloadable_images]
</code></pre>
I use this plugin together with “Enhanced Media Library” (https://wordpress.org/plugins/enhanced-media-library/) which enables a taxonomy on the 
media library (besides other features)
This plugin implements a custom thumbnail size of 300px width so probably you will have to regenerate thumbnails too. As a minimum for the 
photo’s shown if they are already uploaded. New uploaded photo’s will generate this thumbnail automatically.

downloadable gallery
