Explorer on the fly graphic update problem - help

I am using CGI.pm and GD to make a page that generates a diagram based
on some form input. The problem I have is under IE (Netscape seems to
work correctly) the new graphic that is generated is not displayed
when the user clicks the submit button and a new page is delivered.
However, if you click the refresh button in the toolbar - it does.
This indicates to me that the JPEG is actually created on the server,
but the browser is displaying a locally cached version. Any thoughts
on how I can force the browser to display the new graphic? I have
tried making the meta tag for the HTTP header have an expire date of
"-1d" and "now", with no change (I think that really only works for
the HTML, not the referenced graphic.)

Any help , clues, leads appreciated.
