Question about introimage

I have one tour in the latest version 1.08.15, and I added the introimage, like the example into documentation. All works fine, except that I want that introimage only open at the start of the tour, and if you do click again on the first pano, the introimage not open
The code is

url="pano_help.png"
align="center"
onloaded="set(alpha,0); tween(alpha,1);"
onclick="hideintroimage();"
/>

if(layer[introimage].enabled,
set(layer[introimage].enabled,false);
tween(layer[introimage].alpha, 0.0, 15.5, default, removelayer(introimage));
);
</action>

gyro="true"
/>

is that possible?
What I should add the code to make that happen?

Thanks Ramiro</include>

solved, I found the solution here in the forum

"put all the introimage related stuff outside of the <scene> tags,
and add keep="true" to all related elements,
then it should show only once,

best regards,
