I have some user-created images that I wish to host/serve but only for as
long as people actually use them. I have came-up with the idea of using PHP
to "touch" the files and change the files "modified on" date. This will
enable me to see which files arent being used anymore and delete them from
my server.

In order to do this, I need apache to rewrite say:
*.jpg

to:
filemod.php?file=*.jpg

I think that this would need a rewrite in a .htaccess file residing in the
..jpg's specific folder (.jpgs in other folders dont need processed) but
having never done a rewrite and not really knowing what all the symbols
do... I would like to know how I do this... how it should look... and most
importantly... why? (What each symbol or group of symbols mean)

Sorry this is alot to ask... but thanks for reading

I've a better idea: check in the log files. When an image doesn't show
up anymore for a couple of days you can delete it.

I'd rather learn how to use the built-in methods of Apache (namely rewrite)
to let me do more processing than a simple log-watcher is capable of doing.
Then the same thing script could be used for instance to deny images if the
referer isnt in my domain, only allow access to images if the person is
logged-in, etc.

If there is anyone reading that knows how to use Apache's rewrite
function/method then please read the original post.
This reply wasnt a viable alternative, sorry
