TextFlow img / problem !

Question

Dear friends in Adobe,
There is a simple question here:
When we are using textFlow in our project, and when we want import some html tags in it, specially when our textFlow obj. is in a Module, for example:
<mx:Module xmlns:fx="http://ns.adobe.com/mxml/2009"
     xmlns:s="library://ns.adobe.com/flex/spark"
     xmlns:mx="library://ns.adobe.com/flex/halo"
     layout="absolute" width="100%" height="100%"
     creationComplete="func();">
     <fx:Declarations>
          <!-- Place non-visual elements (e.g., services, value objects) here -->
     </fx:Declarations>
     <fx:Script>
          <![CDATA[
          import flashx.textLayout.conversion.TextConverter;
          internal var Pvar:String = new String();         
          public function func():void{         
               Pvar = "<TextFlow xmlns='http://ns.adobe.com/textLayout/2008'>"+
                      "<div><span color='#ff0000'>some text here</span><br />"+
                      "<div><img id='img1' source='Sunset.jpg' /></div>"+
                      "</div></TextFlow>"
               rtxt.textFlow= TextConverter.importToFlow(PoetsBCvar2, TextConverter.TEXT_LAYOUT_FORMAT);              
          ]]>
     </fx:Script>
     <s:RichText id="rtxt" />
</mx:Module>
everything is allright, except showing the image file !
and it will shown if we set both of width and height attributes in the <img... tag, just like this:
"<div><img id='img1' source='Sunset.jpg' width='100' height='100' /></div>"
I wonder if it could show the image without setting these attributes in default size, that was not so better and easier?!
