SYNOPSIS

10       xscreensaver-getimage-file  [--verbose]  [--no-cache]  [--flush-caches]
11       directory-or-URL

DESCRIPTION

14       The  xscreensaver-getimage-file  program  is  a  helper program for the
15       xscreensaver hacks that manipulate images.  It is invoked  by  xscreen‐
16       saver-getimage(6x) as needed.
17
18       It prints the name of a randomly-selected image file.  The directory is
19       searched recursively.  Non-image files and images smaller than  500x500
20       are excluded.
21
22       The directory may also be the URL of an RSS/Atom feed.  Enclosed images
23       will be downloaded and cached locally.
24
25       The contents of the directory are cached, for performance.   The  cache
26       is re-generated if 3 hours have passed.

OPTIONS

30       xscreensaver-getimage-file accepts the following options:
31
32       --verbose
33           Print diagnostics.
34
35       --no-cache
36           Ignore the cache when searching for images.  This may be slow.
37
38       --flush-cache
39           Discard  all  caches  immediately.   They  will  be re-generated as
40           needed.
41
42       directory-or-URL
43           If it is a pathname, it will be searched recursively for images.
44
45           If it is a URL, it should be an RSS or Atom feed, or an  HTML  page
46           whose metadata links to its feed.  All of the feed's images will be
47           downloaded to a local cache.  The URL will  be  re-polled  periodi‐
48           cally, downloading any new images and removing expired ones.
