NAME

       xscreensaver-getimage-file - put a randomly-selected image on the root window

SYNOPSIS

       xscreensaver-getimage-file [-display host:display.screen] [--verbose] [--name] [--no-cache] directory-or-
       URL

DESCRIPTION

       The xscreensaver-getimage-file program is a helper program for the  xscreensaver  hacks  that  manipulate
       images.   Specifically,  it  is  invoked by xscreensaver-getimage(1) as needed.  This is not a user-level
       command.

       This program selects a random image from disk, and loads it on the root window.  It does this by figuring
       out which image-loading programs are installed on the system, and invoking the first one it finds.

OPTIONS

       xscreensaver-getimage-file accepts the following options:

       --verbose
           Print diagnostics.

       --name
           Don't load an image: instead just print the file name to stdout.

       directory-or-URL
           If  a  directory  is  specified,  it  will be searched recursively for images.  Any images found will
           eligible for display.  For efficiency, the contents of the directory  are  cached  for  a  few  hours
           before it is re-scanned.

           If a URL is specified, it should be the URL of an RSS or Atom feed containing images.  The first time
           it is accessed, all of the images in the feed will be downloaded to a local cache  directory.   If  a
           few  hours  have  elapsed  since  last time, the URL will be polled again, and any new images will be
           cached, any images no longer in the feed will be expired.

       --no-cache
           Update the cache immediately, even if it is not time yet.  This will re-scan the  directory,  or  re-
           poll the RSS feed.
