The best approach to embed a SWF into a HTML page is to use SWFObject.
An example from the documentation:
Where I found it: http://stackoverflow.com/questions/1...in-a-html-page
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<title>SWFObject dynamic embed - step 3</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
swfobject.embedSWF("myContent.swf", "myContent", "300", "120", "9.0.0");
Google is the answer to life.
