downloadable gallery
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/
code court
[downloadable_images taxonomy="gallery" slug="wallpaper"]
The default for taxonomy is gallery, the default slug is « wallpaper ». So the above could also be used as
[downloadable_images]
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.
