Get Lightbox or similar image viewer integrated in Flash

Hello!

I have a problem that I hope can be solved.
I’ve made ​​a website entirely in Flash, and on one of the subpages I need an image gallery. If you click on a thumbnail you should open a picture viewer that displays the image in a larger format (popup window).
If you use html (not Flash) I know that for an example Lightbox is super easy to setup. It’s just to add some scripts in the html document and in Dreamweaver link between the thumbnail and the large picture.
But now when I open my flash page in Dreamweaver the site is of course an swf file and as far as I know you can not add anything “over” the swf file.
If I try to insert an image in the document, the image is placed outside the swf-file window.

I’ve Googled a lot about this, and there should be a solution, but I have unfortunately not found any good guide yet.

What I need to know is what code that should be inserted into Dreamweaver (HTML) and also what code that should be inserted into Flash (ActionScript).

I would be very grateful if someone could help me with this problem.
