I have this same issue – I would love to know the solution! I love this plugin, but this is the final piece to get it fully integrated into my client’s website.
If you want to use the shortcode, you can specify a specific category or tag to include images from it (see the question in the FAQ). If you want to simply query for media items of a certain category, you can use WP_Query
for that, just like anywhere else. This is explained more closely in the WP_Query
documentation. As taxonomy
there you’d have to provide attachment_category
(since that’s the internal slug of the categories used for attachments).
