<DIV><FONT face=Arial size=2>It appears that Mozilla/Firefox has a bug or
limitation that causes the browser to cache JPEG snapshots
unconditionally, i.e. they ignore that HTTP header that you added a while

Javascript event handler, nothing changes.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
