Making a site without external .swfs

hi all,

i’ve made a few sites in flash (not very good but they work ;)) and what i’ve done is basically like the kirupa tutorial about preloading says - have a different .swf for each section then code the buttons to load them.

however, it seems to me that a lot of sites don’t really use this anymore… i’m thinking in particular of www.24-7media.de, which, as far as i can tell, has all the sections in one file. The reason i think this is that when you click on a section, it has a textured background, so if there was an external swf, the pattern wouldn’t align properly (hard to explain).

Anyway, if they do have it all in one file, how do they make it so each section still loads separately? I want my site to load in sections (so it’s not such a big wait at the start) but without using external .swf’s, is this possible?

thanks a lot
i know there’s SOOO many questions about preloaders and stuff, but i couldn’t find any that apply here…
