I would say open your flash editor and edit it on the stage.
You would have to know flash.
The text.html is referenced in the fla file.
The template is made for minimal work on your part. Changing text and pics to get it up on the web.
You could swap out the pics in the images directory, but that will only keep them in the same spot.

He did say html
But we were both wrong as we did not read the question.
