i want to avoid using <embed> tags so i used data="flashMovie.swf" so i can see the flash in fireFox.

but if i want to get rid of the grey triangle that shows in IE6 i used to use a
javascript link after the flash tags in my html :

  <script type="text/javascript" src="ieupdate.js"></script>

and the javascript is:

theObjects = document.getElementsByTagName("object"); 
for (var i = 0; i < theObjects.length; i++) { 
theObjects[i].outerHTML = theObjects[i].outerHTML; 
}

but using the data and the above together prevents the flash to shoe in IE6
and IE7.

any idea how i can solve this?

Look at the stickies in the HTML forum, there's 1 thread devoted to adding flash and other media to a page.
