Is it possible to preload in sections?

1

I currently have a site that is growing and becoming too many single .swf files. I probably have close to 70 and have at least another 50 to go. What I am doing is putting an image then a small description under it with a previous/next button to navigate. Well its getting to be too much to keep creating/saving/publishing these things over and over, so im wondering if I could dump all of this in one swf and preload certain areas as needed. It would be far too big to preload the entire thing but if I could just make it preload certain frames when required to view that content Im sure that would alot easier to work with than what im doing now. Any suggestions will be appreciated.
