Vercinstex sei gentilissimo.
Allora ho inserito questo codice:

<P align=center>
<OBJECT classid="clsid:d27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/
swflash.cab#version=5,0,0,0" WIDTH=1200 HEIGHT=700 >
<PARAM NAME=movie VALUE="http://www.webalice.it/alessandro.1973/gallery2.swf?xmlPath=http://www.webalice.it/alessandro.1973/gallery_data5.xml">
<PARAM NAME=quality VALUE=high>
<EMBED src="http://www.webalice.it/alessandro.1973/gallery2.swf?xmlPath=http://www.webalice.it/alessandro.1973/gallery_data5.xml"quality=high WIDTH=1200 HEIGHT=700
TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?
P1_Prod_Version=ShockwaveFlash"></EMBED>
</OBJECT>

ma non so perchè ebay (la pagina dove inserisco le inserzioni html in ebay) l'ha trasformato così:

<OBJECT codeBase="http://download.macromedia.com/pub/shockwave/cabs/flash/ swflash.cab#version=5,0,0,0" height=580 width="90%" classid=clsid:d27CDB6E-AE6D-11cf-96B8-444553540000><PARAM NAME="_cx" VALUE="21749"><PARAM NAME="_cy" VALUE="15346"><PARAM NAME="FlashVars" VALUE=""><PARAM NAME="Movie" VALUE="http://www.webalice.it/alessandro.1973/gallery2.swf?xmlPath=http://www.webalice.it/alessandro.1973/gallery_data5.xml"><PARAM NAME="Src" VALUE="http://www.webalice.it/alessandro.1973/gallery2.swf?xmlPath=http://www.webalice.it/alessandro.1973/gallery_data5.xml"><PARAM NAME="WMode" VALUE="Window"><PARAM NAME="Play" VALUE="0"><PARAM NAME="Loop" VALUE="-1"><PARAM NAME="Quality" VALUE="High"><PARAM NAME="SAlign" VALUE="LT"><PARAM NAME="Menu" VALUE="-1"><PARAM NAME="Base" VALUE=""><PARAM NAME="AllowScriptAccess" VALUE=""><PARAM NAME="Scale" VALUE="NoScale"><PARAM NAME="DeviceFont" VALUE="0"><PARAM NAME="EmbedMovie" VALUE="0"><PARAM NAME="BGColor" VALUE=""><PARAM NAME="SWRemote" VALUE=""><PARAM NAME="MovieData" VALUE=""><PARAM NAME="SeamlessTabbing" VALUE="1"><PARAM NAME="Profile" VALUE="0"><PARAM NAME="ProfileAddress" VALUE=""><PARAM NAME="ProfilePort" VALUE="0">
