Preloading for dynamic content

Hey All,

my flash site is comprised of about 10 to 12 dynamically loaded external images, which are declared as Loader class instances, loaded, then placed on the stage. i set up a basic external pre-loader but just as i suspected it would, the pre-loader loads the swf of my main site but when the swf is loaded the external dynamic content of the main site still has to be loaded… how can i go about pre-loading dynamic content? because what i want is all the assets that make up the site to be there and loaded, when the pre-loader is done.

thanks for any help in advance
