NYCPHP Meetup

I recently came accross a new feature added by photos.com. They allows
the users to search images based on the color.

They are using linux server and i hope it is done in php. Anybody has
any idea how this is implemented. I don't think they are accessing the
image files each and every time - they might be storing the color info
in the db. Any idea how this can be implemented. This is not a
requirement i'm facing - just curios.....
