<p>The plugin adds two taxonomies to the WordPress media library which are then available to categorize and tag your attachments. By default, these taxonomies, although sharing the same names and behavior, are separate from the default post taxonomies, but this can easily be changed if desired.</p>
<p>The plugin follows WordPress Core principles and offers a lightweight alternative to similar approaches which often tend to be incredibly flexible, but at the same time complicated and bloated. And if you have a little knowledge of code, you should be able to adjust the plugin exactly to your needs if the default configuration doesn’t satisfy you.</p>
