Q:

Assign A Category To An Image In Wordpress

I thought my question would have a fairly simple answer, but my research has proven otherwise.  What I would like to know is if there is a way that I can assign a category to an image in my library on my Wordpress site?  To be even more specific, I am not referring to applying a thumbnail image to a category page, or post of a certain category.  I have a category named "slider", and I want to be able to apply that category to images in my library.  Thanks! 

A:

Yes, it is possible. 

Media Tags

Provides ability to tag media/attachments via Media Management screens

Media Categories

Easily assign categories to media with a clean, simple, and searchable category meta box.  Then use the gallery shortcode to display category galleries

Media Category Library

WordPress plugin that allows items in the Media Library to be assigned to a category.

One problem is that WordPress 3.5 made a complete revamp of the Media Management and past solutions may or may not work...
