seiten, die obigen code einbinden, muessen dann natuerlich noch die slideshow-daten
zur verfuegung stellen - beispielsweise so:

//console.log("YAHOO.AOWLB.importSlideShowData : " + YAHOO.AOWLB.importSlideShowData);  
  console.log("SlideshowPlugin.importSlideShowData : " + SlideshowPlugin.importSlideShowData);  
  
//YAHOO.AOWLB.importSlideShowData([
