Slideshow of SWF files

So I’m not AS2 pro, but I made a slideshow that loads about 15 different SWFs as each slide. Each SWF has a preloader and a “container” blank movie clip at the end which loads the next SWF. On the last SWF I have it reload the first SWF in the root “container”. Now I’m not sure if this is the best way of doing this, but to me it sounds like it stacks a bunch of loaded SWFs on top of each other. Will doing something like this effect performance? Is there a better solution? Thanks!<3
