Was mache ich falsch. Mein Introimage sollte eigentlich nach 2 Sekunden ausblenden.
Hier meine tour.xml:

<events name="panoevents"
onloadcomplete="delayedcall(2, if(layer[introimage], hideintroimage() ); ); set(events[panoevents].onloadcomplete,null);"
/>

<action name="hideintroimage">
if(layer[introimage].enabled,
set(layer[introimage].enabled,false);
tween(layer[introimage].alpha, 0.0, 0.5, default, removelayer(introimage));
);
</action>


<action name="startup">
if(startscene === null, copy(startscene,scene[0].name));
loadscene(get(startscene), null, MERGE);
</action>
