Easily assign categories to media with a clean, simple, and searchable category meta box. Then use the gallery shortcode to display category galleries
Allows users to assign categories (or other taxonomy terms) to items in their Media Library with a clean and simplified, searchable version of the standard category meta box. The "Search Categories" field allows you to narrow your search for a category as you type - this functionality is not native to WordPress but is instead borrowed from Jason Corradino's Searchable Categories plugin.

Since WordPress 3.5 now supports attachment taxonomy, the work of adding a metabox to the attachment editor is happening entirely inside of WordPress. This is great, and we now have true metaboxes for taxonomy - they core team has also accepted my patches which caused several headaches for this plugin. Media Categories 1.5 takes advantage of the new Media Modal - with this plugin, you can now edit a images categories directly from the modal screen. I've also fixed some long standing bugs with the shortcode gallery functionality.
