Best structure for a "fancy slideshow"

hello all
I have a series of 12 digital paintings that i have done that i need to incorprate into a flash site.
the plan for the site is very simple, basicly a “fancy slide show” with buttons & rollovers for a next and previousimage.
(perhaps a “yet to be determined” transition between images)

so pretty simple, the only thing that i see that might cause me a problem is that the images are pretty hi res , so with that in mind i think it would be a good idea to have a preloader before every image

anyways the way that i have it set up now is that all the images are different movies, and i just tell flash to play “movie2” when user clicks “next1” / play “movie 3” when user clicks “next 2” so on so forth

ok thats pretty much it

can anyone help with suggestions or comments on setting this up.

Thanks all!
