Support for Flash Video Thumbnails

Flash videos usually have thumbnails associated with them. I'd like the thumbs to be saved in such a way that they can always be recognized as the video's thumb. This way, I don't have to specify flashvars every time I show that video to get a thumb.

I'm not sure what's the best solution for this but some ideas I had were...
- integration with Image and Image Attachment module?
- some way to make the thumb image a node as well

This allows the thumb to have access to Views as well!
