Swap image w/ flash movie

I have a nav bar with rollovers and also with the swap image feature that is
displaying another image on the other side of the page when the button is
moused over and it works fine. I want to have one of those buttons not only
rollover but also in the area I have designated for the swap image on the other
side of the page, I would like a flash file to play when that certain buton is
moused over.
Is this possible?

I've been searching for a similar solution. I'm looking for a way to have an
image swap to a flash movie after the page loads. this would allow a user to
view the page content first and then wait for the flash content to download if
they are interested in it. i'm looking for a way to do this with
dreamweaver's built in javascript behaviors but i don't think it's going to
work without some custom code.
