blogger will not accept .swf files as uploads (AFAIK), so I uploaded this to a wikispaces wiki and use the path to that file in the html snippet: <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" width="550" height="400" id="colorin" align="middle"> <param name="allowScriptAccess" value="sameDomain"> <param name="movie" value="http://sandaig.wikispaces.com/space/showimage/faces_scrub.swf"> <param name="quality" value="high"> <param name="bgcolor" value="#FFFFFF"> <embed src="http://sandaig.wikispaces.com/space/showimage/faces_scrub.swf" quality="high" bgcolor="#FFFFFF" width="550" height="400" name="colorin" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer"> </object> you migh need to play with the sizes? You have to ignore the tag not closed error when publishing too.
