Not sure, I don't use iWeb. If anyone has used SimpleViewer with iWeb, please add a comment here.

Thanks varkgirl!

The links varkgril posted work well. It took me a few hours to get it to work.
I have 2 tips that will help.

1.) Make sure you create a text box in iWeb for creating your iframe box. Do not make a shape/picture box.

2). When you open your iweb html page in TextEdit, go to your "iframe_code_here" text. You will have to remove the font information in the 1-2 lines in front that point. This part was left out from the tutorials.

Good luck and thanks for sharing the tips here.

nevermind.

I figured it out. To make the simpleviewer background transparent with an iframe, you have to go to the simpleviewer index.html file. Half way down in the code look for "body" you have to delete the lines for background-color.

Then under:
var fo = new SWFObject("viewer.swf", "viewer", "100%", "100%", "7", "#000000");

Add this:
fo.addParam("wmode","transparent");

In all the posts I have read about adding "wmode", "transparent" , no one mentioned that you have to delete the line regarding background-color. It took a few hours until I got lucky and took a guess at deleting that line.

Hope this helps others,
