loadmovie into a tween

[HotMadras]

I'm using Flash 5. I've got a "gallery" type tween which moves a series of pictures horizontally across the screen in a loop. For the sanity of my users, I want to streamline it somewhat because it's pretty huge. What I want to do is load the individual pictures while the main tween is running first time around, so that there's something for the user to look at while the rest loads. I've managed to tweak the tween so that I can access targets within it (I made it into a movie clip instead of a graphic, which seems to have worked), and I can get the pictures (converted to swfs) to load into the tween for the first loop. However, the tween seems to forget the pictures for the second and subsequent loops.

Does anyone have an authoritative howto on using loadmovie to insert content into a tween on the fly? Or any other method of achieving a kind of streaming on the tween, so that users don't have to wait for the whole thing to load?

Thanks
