swf in forum annocement

[PuntoPower]

hi

hope this is the right forum,

what im tryin to achieve is have a swf banner on a selected few sub forums in my forum.

one way i tried is to use an annocement and as the decription insert the following code

<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"
WIDTH="468" HEIGHT="60" id="blitz">
<PARAM NAME=movie VALUE="http://www.racershaven.com/flyer/blitz.swf">
<PARAM NAME=quality VALUE=high>
<PARAM NAME=bgcolor VALUE=#FFFFFF>
<EMBED src="http://www.racershaven.com/flyer/blitz.swf" quality=high bgcolor=#FFFFFF WIDTH="468" HEIGHT="60"
NAME="myMovieName" ALIGN="" TYPE="application/x-shockwave-flash"
PLUGINSPAGE="http://www.macromedia.com/go/getflashplayer">
</EMBED>
</OBJECT>

it does work if inserted in a basic html file and looked up in a browser but when inserted into the annocment descritption the page hangs.

if i insert html img to a picture it shows but why doesnt the swf???

or is there another way to do this or is there a hack out there that allows a image/object to be seen in certain forums and not others

plz help
