Preload SWF + external images

Ok, I’m in need of some advice here. Let’s say I have the following situation… a SWF that will serve as the main movie for the site. Inside this SWF, I have a script that loads a JPG into a holder MC that’s on stage. So basically it’s like this:

  • main.fla
    – holder_mc (this isn’t an empty MC, it has some PNG’s inside)
    — external JPG loaded in by loadMovie

I’m ok with building a preloader for the holder_mc and the rest of the FLA (without the size info of the external JPG), but how would I incorporate the size of the external JPG into my initial preloader before I actually start playing everything.

Would I have to set the holder_mc visibility to false, call the loadMovie, initiate the preload, and then set visibility back to true. There’s gotta be a better way? :wink:

Cheers!
