Embed SWF over the top of the page…

Hello everyone!

I can usually navigate my way around WP very well. But I have a client who has thrown a massive curveball at me and so I need your expert help!

I built https://www.yvonneadele.com using WP and a theme called Revival from Viva Themes.

Everything is working just fine and I’ve been able to manipulate the CSS to where we need it to be.

Now what my client would like to do is include a swf file that automatically plays and then disappears like this mockup done for her by iPresent.

The instructions that were sent with the files are located here.

So I have a few questions:
a) how can I create the transparency that is going to be required to make this swf work on the homepage of https://www.yvonneadele.com?
b) where do the files need to be located on the server in order for them to work?
c) what script should I use in index.php to make all of this happen?
d) how can I set the swf to play at the right horizontal/vertical location given that the site is centred (but fixed width for the main body of the site)

Any insights or help would be SO SO SO appreciated!!

Thank you!!!
