Comment (by lancewillett):

 Second pass at patch introduces two new functions:

 {{{get_random_header_image()}}}

 and

 {{{is_random_header_image()}}}

  * Check if random header image is in use.
  * Always true if user expressly chooses the option in Appearance >
 Header.
  * Also true if theme has multiple header images registered and no
 specific header image is chosen.

 Theme does not have to explicitly add support for this feature—all that's
 needed an array of registered images.

 In Appearance > Header form, show the random image option if this theme
 has multiple header images. The option is checked by default if no header
 has been set.
