Handy little class for attaching arbitrary media files (images, audio, video, etc.) to events in a timeline application. It does a couple of nifty things for supporting the varying media types:

The before_post_process method ensures we attempt to generate thumbnails only for images.

The named scopes along with the set_item_type callback gives us a way to pull out media items of a certain type, without having to go down the often more-trouble-than-it's-worth STI path.
