Media thumbnails?

[canadianbacon11]

Is there a way to have QS show thumbnails of photos/videos that are
stored in various places?  I like using QS to locate things I'm
looking for, but sometimes I'll get to a folder of photos and have to
open it in finder because I can't see what the photos look like.  Is
there a way to get thumbnails to replace the icon for photos and
QuickTime-compatible videos?
