   BACKGROUND IMAGES — frame sample closeups
   ------------------------------------------------------------
   1. Make a folder called  images  next to your html files.
   2. Put a photo in it, e.g.  images/hero.jpg
   3. Set the matching filename below.
   Leave a value as  none  to keep that section solid black.
   A dark tint sits on top automatically, so white text stays
   readable over any photo.
