XScreenSaver(1)

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.
