Flash Dynamic Text Field - Embeded Image Shrink and Stretch when appying width and height to dynamic text field

Question

Pardon me if this post was already answered in any post or forum, I tried searching but could not able to find any solution. Please help!

ACTION SCRIPT CODE

private function addContent ($mcBox,$x,$y,$w,$h):void
{
   if($mcBox.getChildByName("TextAreaMC")){
    $mcBox.removeChild($mcBox.getChildByName("TextAreaMC"));
   }

   var padding=10;

   var textArea:TextField=new TextField();
   textArea.name="TextAreaMC";
   textArea.x=padding;
   textArea.y=padding;
   textArea.border=true;
   textArea.width=$mcBox.width;
   textArea.width=$mcBox.height;
            textArea.wordWrap=true;
   textArea.condenseWhite =true;
   textArea.multiline=true;
   textArea.wordWrap=true;

   textArea.styleSheet=_css; //apply external css
   textArea.htmlText=_content; // write the content

   $mcBox.addChild(textArea);

}

HTML FILE CONTENT

<img src="files/someimages.png" id="cardImg" hspace="30" vspace="20" width="118" height="113" align="right" /><p class="head">Some Heading</p>
