Insert SWF into FLA

Hi Guys,

Its been a while since my last post and i apologise if this has come up before, but what im basically trying to do is insert (not load) a swf into my main fla file. I have my home page (index.fla) and i’ve downloaded this cool image viewer or slideshow, and i want to insert that into my index.fla file.
What I’ve tried so far…
I’ve inserted a movie clip and named it imageViewer, I then imported (to stage) viewer.swf. This does not work. Something that looks nothing like the image viewer briefly pops up when i run index.fla.

Any help would be greatly appreciated
