header and no refresh

I'm allowing a user to update their profile. In their profile, they can upload a picture. I store the picture as there userid plus the correct extension. The problem is that when they upload a new pic with the same extension as the old pic, it doesn't show the change until they either refresh the screen or close and reopen the browser. I tried to send the following headers: header("Pragma: no-cache"); header("Cache-Control: no-cache, must-revalidate, pre-check=0"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Expires: " . gmdate("D, d M Y H:i:s") . " GMT"); They get set just fine(checked phpinfo) but the image still gets cached. Is there a way to get the image to not cache? If it matters, the image is stored in a directory and the path is stored in a mysql database. Any help is greatly appreciated. Jason Stechschulte jpstech@nc.edu
