I did this on another site...
Make 2 Flash files: 1 with the loading animation and one without. In your theme.html, you can do something like this:
<{if $xoops_isuser == false}>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="733" height="112" align="top">
<param name="movie" value="<{$xoops_url}>/flash/guestflash.swf">
<param name="quality" value="high">
<embed src="<{$xoops_url}>/flash/guestflash.swf" width="733" height="112" align="top" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash">embed>
object> <{else}> <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="733" height="112" align="top">
<param name="movie" value="<{$xoops_url}>/flash/userflash.swf">
<param name="quality" value="high">
<embed src="<{$xoops_url}>/flash/userflash.swf" width="733" height="112" align="top" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash">embed>
object> <{/if}>
That way Guests continue to view the loading animation as they browse the site, but Members get to view the flash w/o the loading animation.
Hope this helps :)
