Embedding images in textbox

Hello, can anyone help please?! I’ve been following Kirupa’s tutorial : http://www.kirupa.com/developer/mx/multiple_dynamictext.htm so I can load an external text file into a text box in flash. All that works fine but I’m having problems trying to embed a jpg into it. I have been searching the web and all I’ve found is that you use the “<img src>” method as you would with any html document. From what I have read, you place that code into the .txt file like I have done:

content=B. Clarke 12sg.
<img src=“images/misc/briantech.jpg”>
Sifu B. Clarke receiving his 1st Tech grade by Keith Kernshpect

This is still not working! can anyone help? I have followed kirupa’s tutorial (http://www.kirupa.com/developer/mx/multiple_dynamictext.htm) exactly and the only change I have made is changing the word “myNews” to “content” in the AS and start of .txt file.

Thanks
