De todas maneras siempre esta la solucion de escribir el codigo:
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" width="100%" height="86" hspace="1" vspace="1" alt="Texto">
<param name="movie" value="banner%20principal.swf" />
<param name="quality" value="high" />
<param name="SCALE" value="exactfit" />
<param name="BGCOLOR" value="#000000" />
<embed src="direccion" width="100%" height="86" hspace="1" vspace="1" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" scale="exactfit" bgcolor="#000000"></embed></object>
