Rails spinoffs - Aug 2007 - firefox browser caching images [ajax.periodicalupdater]

Hi ,
I am using ajax.periodicalupdater to update some content on a webpage.
But the problem is that it the browser is caching the images and is
not updating them with the latest ones. How can i prevent the browser
from caching the images .
thanx
Sumeet

You can configure your server to have them expire,
read here for info on apache .htaccess configs:
http://www.askapache.com/htaccess/speed-up-sites-with-htaccess-caching.html

(I have not tried this)
Make all files no cache, inside .htaccess file add:

<Files *>
Header set Cache-Control: "private, pre-check=0, post-check=0, max-
age=0"
Header set Expires: 0
Header set Pragma: no-cache
</Files>

or you can simply append a unique id to your image url
