Midtstilling af flash'en i html'en

Hej
Har publisheret min Flash med FLash Detection, og derfor ser min html bl.a. ud som nedenfor. Hvordan får jeg proppet noget formateringskode ind så min Flash blir centreret?


<script language="JavaScript" type="text/javascript">
<!--
var hasRightVersion = DetectFlashVer(requiredMajorVersion, requiredMinorVersion, requiredRevision);
if(hasRightVersion) {  // if we've detected an acceptable version
    var oeTags = '<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"'
    + 'width="960" height="630"'
    + 'codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab">'
    + '<param name="movie" value="mestergull_design_selv_web.swf" /><param name="loop" value="false" /><param name="quality" value="high" /><param name="bgcolor" value="#ffffff" />'
    + '<embed src="minflash.swf" loop="false" quality="high" bgcolor="#ffffff" '
    + 'width="960" height="630" name="mestergull_design_selv_web" align="middle" valign="center"'
    + 'play="true"'
    + 'loop="false"'
    + 'quality="high"'
    + 'allowScriptAccess="sameDomain"'
    + 'type="application/x-shockwave-flash"'
    + 'pluginspage="http://www.macromedia.com/go/getflashplayer">'
    + '<\/embed>'
    + '<\/object>';
    document.write(oeTags);  // embed the flash movie
  } else {  // flash is too old or we can't detect the plugin
    var alternateContent = 'Alternate HTML content should be placed here.'
      + 'This content requires the Macromedia Flash Player.'
      + '<a href=http://www.macromedia.com/go/getflash/>Get Flash</a>';
    document.write(alternateContent);  // insert non-flash content
  }
// -->
