A quick and dirty untested shell script:
#!/bin/bash
WALLFILE=images_wall.html
LOGFILE=/var/log/squid/access.log
NB_IMG=50
SLEEP=10
while :
do
echo "<HTML>" > $WALLFILE.tmp
echo " <HEADER>" >> $WALLFILE.tmp
echo " <TITLE>Images Wall</TITLE>" >> $WALLFILE.tmp
echo " <META HTTP-EQUIV='REFRESH' CONTENT='$SLEEP'>" >> $WALLFILE.tmp
echo " </HEADER>" >> $WALLFILE.tmp
echo " <BODY>" >> $WALLFILE.tmp
awk ' { print $7 } ' $LOGFILE |
grep "jpg$\|gif$" |
tail -$NB_IMG |
while read URL
do
echo " <IMG SRC='$URL'>" >> $WALLFILE.tmp
done
echo " </BODY>" >> $WALLFILE.tmp
echo "</HTML>" >> $WALLFILE.tmp
mv -f $WALLFILE.tmp $WALLFILE
sleep $SLEEP
done
Needs to be adapted to your access log format (the $7 in awk is the 7th (url)
column in the logfile lines)...
You can also put it in cron and remove the main while loop and the sleep.
