 a few months ago I opened a thread here on that same subject. I wrote a
little shell script that I run via .xinitrc - it selects background images
from a directory and changes them randomly - each workspace gets its own
image. You can send a SIGHUP to trigger immediate change of wallpapers. The
script has its limits (e.g. the number of workspaces, timeout for changing
wallpapers and the image directory are hard-coded), but it has been working
like a charm for me ever since I set it up. You may take a look at this
code:

#!/bin/sh

SLEEP_PID=0

trigger() {
  echo "Triggering new wallpapers..."
  if [ $SLEEP_PID -gt 0 ]; then
    CMD="kill $SLEEP_PID"
    echo "$CMD"
    $CMD
  fi
}

quit() {
  echo quit
  exit 0
}

trap trigger SIGHUP
trap quit SIGTERM

cd /usr/local/share/backgrounds/Variety/
while true; do
  w=0
  date
  find . | sed 's/^\.\///' | sort -R | while read i; do
    test -d "$i" && continue
    case "$i" in
      keep-ratio*)
        CMD="wmsetbg -f -w $w"
        ;;
      *)
        CMD="wmsetbg -w $w"
        ;;
    esac
    echo "$CMD $i"
    $CMD "$i"
    w=`expr $w + 1`
    if [ $w -gt 6 ]; then
      break
    fi
  done
  sleep 10m &
  SLEEP_PID=$!
  wait $SLEEP_PID
done
