I found this script on the web and modified it a little for DSL.  As shown here it will use /home/dsl/.fluxbox/backgrounds/ for the images.  I saved this code as setrandbg.sh and made it executable.

[CODE]
#!/bin/sh
# by Benjamin Okopnik <ben-fuzzybear@geocities.com>
# *** bkgr *** - A random background selector for XFree86

# Define the dir where the pictures are kept
PIC_DIR=/home/dsl/.fluxbox/backgrounds

# Create a unique tempfile name and save all PIC_DIR filenames into it
TMPFILE=$(mktemp /tmp/temp.XXXXXX)
ls $PIC_DIR/* > $TMPFILE 2> /dev/null
for ((  i = 0 ;  i <= 0;  i  ))
do

# A) Gen a random # (0 - 32767). B) Confine it to a range of (1 - <picfile_count>).
# C) Set $FNM to the filename on line $RANDOM in the $TMPFILE.
FNM=$(head -$(($RANDOM / (32768 / $(grep -c . $TMPFILE)) + 1)) $TMPFILE | tail -1)

# This allows a pic name to be entered as an arg to bkgr - "Honey! You
# should see this KEWL background that came up!" Anyway, check if the
# file exists (if an arg is entered) and substitute it for the random one.
if [ -f $PIC_DIR/$1 ]
then
   FNM=$PIC_DIR/$1
fi

# Tell me the name for future reference - or, provide a doublecheck if
# I do enter an arg ("Yep, I'm using the pic that you specified.")
echo -n "Using "
basename $FNM

# Build in a 'wait-loop' to avoid a race condition with the WM -
# replace "icewm" with your own window manager's name.
while [ -z "$ICE" ]
do
   ICE=$(ps ax | grep fluxbox)
   sleep 2
done

# Handle the pics differently based on size; I've found 20kB
# to be a good breakpoint for my JPGs and PNGs...

   bsetbg -f $FNM &

sleep 5m

done
# Clean up...
rm $TMPFILE


# ...and exit gracefully.
exit 0


# "Y'all come back now, y'hear?"
