I checked your code, and it looks like this:
<img alt="" src="http://www.iadwm.com/content/textpageimages/exterior.jpg" width="300" height="200"><textformat leading="200"><img src="path/image.jpg" width="300" height="200" hspace="0"></textformat><br><br>Chalkwell Hall is ...
You have your image first, and then you just pasted the code that I gave you below. The code I gave you was an example, where you need to fill in the image src path yourself ... It should be like this:
<textformat leading="200"><img alt="" src="http://www.iadwm.com/content/textpageimages/exterior.jpg" width="300" height="200" hspace="0"></textformat><br><br>Chalkwell Hall is...
The <textformat> tag needs to surround your image tag ... I am no 100% sure how this will work though, although it should show the text more or less below the image. The fact is that your image is not full width of the textpage, and by default, flash textfields attempt to wrap an image into the text ...
