Cron runs commands, including scripts. So before I worry about running
something through cron, I make sure the script works as I expect first. You
can easily have a shell script like so (much like most log rotating
scripts):
# swap this so we can make the switch at the end...
mv a.html temp.html
mv b.html a.html
mv c.html b.html
..
mv z.html y.html
mv temp.html z.html

Ever see counter CGIs? An image tag is simply a link--it has to execute the
link to get the graphic. So a CGI that returns an image works inside an
<img> tag. I've seen many ad scripts that work like this...
