Hi dinogomez,
I took a look at the link and it would require some real post publishing modifications to get it to work. I don't have the actual code on the referenced site, nor have I tested it with iWeb, but seems that you would have to add this code to the head section of .html page you want to add it to:
<!-- SWFObject embed by Geoff Stearns geoff@deconcept.com http://blog.deconcept.com/ -->
<script type="text/javascript" src="swfobject.js"></script>
<style type="text/css">
/* hide from ie on mac */
html {
height: 100%;
overflow: hidden;
}
#flashcontent {
height: 100%;
}
/* end hide */
body {
height: 100%;
margin: 0;
padding: 0;
background-color: #000000;
}
</style>
Then add this code into the body of your site:
<div id="flashcontent">
You need to upgrade your Flash Player
This is replaced by the Flash content.
Place your alternate content here and users without the Flash plugin or with
Javascript turned off will see this. Content here allows you to leave out noscript
tags. Include a link to bypass the detection if you wish.
</div>
<script type="text/javascript">
// <![CDATA[
var so = new SWFObject("preview.swf", "fullScreen", "100%", "100%", "8", "#000000");
so.addParam("scale", "noscale");
so.addParam('salign', 'lt');
so.addParam("allowFullScreen","true");
so.write("flashcontent");
// ]]>
</script>
I'd recommend using Coda from Panic Software as a great HTML Editor, or you could just use TextEdit if you check the ignore rich text commands in html files pref.
Hope that helps.
