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.

Using this plugin, you can easily integrate LemonInk into your WooCommerce store just by marking products as downloadable and assigning a master file (the original ebook) to them.
After each purchase LemonInk will create watermarked versions of your ebooks and attach them to user’s order allowing them to easily download their individual copies.
