Here is a bare bones sample to see if this helps you understand better,
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
                  xmlns:s="library://ns.adobe.com/flex/spark"
                  xmlns:mx="library://ns.adobe.com/flex/mx" >
     <s:layout>
          <s:BasicLayout />
     </s:layout>
     <s:Image id="bgImage"
                width="100%" height="100%"
                source="@Embed('path/to/image.jpg')"
                scaleMode="stretch"/>
     <!-- Continue Adding elements to your site below this -->
</s:Application>
