Jasper Report html output Image shows cached image in IE and Firefox but works all fine in Chrome
===

I have produced a jasper report in my application (JSF1.2,RichFaces 3.3.3,Portlet bridge), but I am facing a problem, that the image produced by jasper is not changing dynamically even by rerendering its area. After a lot of discussions and analysis I have concluded that because the jasper provides image(new and old) with the same name... Hence browser is not loading this image again and getting this image from the cache. I have also added the following code in the head section of the xhtml(portlet) but the result is still not changed.

    <meta http-equiv="Cache-Control" content="no-cache"/>
    <meta http-equiv="Cache-Control" content="no-store"/>
    <meta http-equiv="Pragma" content="no-cache"/>
    <meta http-equiv="Expires" content="-1"/>

Please let me know, if someone has a solution for it.
Thank you
