<STYLE>
.time       { behavior: url(#time); }
anim\:DA    { behavior: url(#default#anim); }
</STYLE>
<OBJECT ID="time" CLASSID="CLSID:476C391C-3E0D-11D2-B948-00C04FA32195">
</OBJECT>
</HEAD>
<BODY>
<P>Two seconds after the page loads, the image begins to
fade. It disappears after five seconds of animation. This
process repeats itself three times.</P>
<SPAN ID="spanImg" CLASS="time" t:TIMEACTION="visibility" t:BEGIN="2"
t:DUR="5" t:REPEAT="3">
</SPAN>
<DIV ALIGN="center">
<anim:DA ID="da1" STYLE="width:504; height:126; z-index: -1;" />

// Animate the opacity of the image from 100% to 0%, based
// on the progress of the time behavior. Use (1 - progress)
// to get the proper opacity.
