Dynamically Created
This issue becomes irrelevant if the page is dynamically created (e.g. via Perl) at each auto refresh (<META http-equiv="refresh" content="1800").
A little config file could be used to specify the pictures which you could also set up via an HTML page.

Hi!
I have this situation with 3 shellscripts.
One is a "startscript" that simply calls other scripts. This one is scheduled with cron to run at regular intervals. That script runs what I'll refer to as Script 1.
Script 1 in turn runs script 2 (import_catalogs_buyer.sh)

What I have are two text files that I need to shuffle randomly, but I need the two files to be randomly shuffled the same way. I have heard of shuf but I do not know how to use it for two files. Maybe there is also an easy/simple awk command I do not know about that could handle this problem.

xscreensaver-getimage
xscreensaver-getimage(1) XScreenSaver manual xscreensaver-getimage(1)
NAME
xscreensaver-getimage - put some randomly-selected image on the root window
SYNOPSIS
xscreensaver-getimage [-display host:display.screen] [--verbose] window-id [pixmap-id]
DESCRIPTION
The xscreensaver-getimage program is a helper program for the xscreensaver hacks that manipulate images. This is not a user-level command.
This program selects a random image, and puts it on the specified window or pixmap. This image might be a snapshot of the desktop; or a
frame captured from the system's video input; or a randomly-selected image from disk.
If only a window ID is specified, the image will be painted there. If both a window ID and a pixmap ID are specified, then the image will
be painted on the pixmap; and the window may be modified as a side-effect.
OPTIONS
xscreensaver-getimage reads the ~/.xscreensaver file for configuration information. It uses these settings:
grabDesktopImages
Whether it is acceptable to grab snapshots of the desktop. The security paranoid might want to turn this off, to avoid letting people
see (but not touch!) your desktop while the screen is locked.
grabVideoFrames
Whether it is acceptable to grab frames of video from the system's video input. Grabbing of video is done by invoking the xscreen-
saver-getimage-video(1) program.
chooseRandomImages
Whether it is acceptable to display random images found on disk. Selection and loading of images is done by invoking the xscreensaver-
getimage-file(1) program.
imageDirectory
When loading images from disk, this is the directory to find them in. The directory will be searched recursively for images.
It may also be the URL of an RSS or Atom feed, in which case a random image from that feed will be selected instead. The contents of
the feed will be cached locally and refreshed periodically as needed.
If none of the three options are set to True, then video colorbars will be displayed instead.
BUGS
When grabbing desktop images, the window argument will be unmapped and have its contents modified, causing flicker. (This does not happen
when loading image files or video frames.)
