<?xml version="1.0" encoding="utf-8"?>

        layout="vertical"

        backgroundColor="white"> 
  
    <mx:XML id="imagesXML" source="images.xml" /> 
  
    <mx:Zoom id="zoom" /> 
  
    <mx:HBox id="hBox"> 
         <mx:Repeater id="rep" 
                 dataProvider="{imagesXML.image}"> 
            <mx:Image source="{rep.currentItem.@src}" 
                    toolTip="{rep.currentIndex}:{rep.currentItem.@alt}" 
                    completeEffect="{zoom}" /> 
        </mx:Repeater> 
    </mx:HBox>
