ActionScript 3.0 :: Loading Img From Xml, Textfield.height, Scrollbar?

I am loading xml and using Colin Moock's scrollbar as he desrcibes it in Essential Actionscript 3.0. It all worked fine until I tried to put a link to a jpg inside the xml.Where other html tags give no problem, the img seems to mess with the textfield height. I gave the textfield a fixed height but when I try to scroll the field with the image, and trace the textfield height, it increases more and more when I scroll down, messing up the scrollbar.the img tag looks like this (and it loads fine into the textfield):

Code:
<IMG ALIGN= "left" SRC='pics/portret.jpg' WIDTH="200" HEIGHT="207" HSPACE='0' VSPACE='10' />

The slightly adapted scrollbar class looks like this (I gave the scrolltrack a fixed height and tried to give t.height a fixed height too within this class but tracing t.height keeps showing that it is increasing while scrolling down):

Code:
package {
import flash.display.*;
import flash.text.*;[code]..............

So I think that the code or flash doesn't handle the img very well,
