async tree and iconCls

[crosemffet]

I'm making async tree successfully.
server script is:
while($row = pg_fetch_array($rs)){
   $node = array();
   $node['id'] = $row['id'];
   $node['text'] = $row['uname'];
   $node['iconCls'] = 'myCustomIcon.gif'; //not working
   array_push($result,$node);
}
sending from the server the parameter $node['iconCls']='myCustomIcon.gif' is not working. always shows me the default icon.
so the question is: where should I place myCustomIcon.gif to work? is my code ok? is ok to send the custom icon this way?
thanks in advance for your comments,

oops !. sorry, finally I've made it. my mistake, it works like a charm.
solution (just in case other needs): define in jquery/themes/icons.css the icon you want to use with this syntax:
.icon-myIcon{background:url('icons/myIcon.gif') no-repeat;}
then refer it as:
$node['iconCls'] = 'icon-myIcon';
