Serving up images that don't seem to cache
There's a LAPP (postgresql instead of mysql) running over on http://ninjawars.net. I just recently noticed that images don't seem to be caching with any kind of good frequency as I was reloading a page with a few images on it here:
http://www.ninjawars.net/attack_player.php
Here is an example image (they're probably all being served exactly the same):
http://www.ninjawars.net/images/characters/fighter.png
Checking the header, it seems that the caching is set to: Cache-Control:max-age=0
(the full header for this image-like-all-the-others is...

So what modules or config or htaccess or whatever do I change to have it cache images, e.g. for 24 hours?
