ActionScript 2.0 :: Create A New Empty Movieclip To Load An Image?

i'm trying to attach/create a new empty movieclip to load an image into each time my function fires (function has setInterval on it).so far, my code works in that the first time it creates the empty clip and loads the pic in it, measures the loaded bytes and alpha fades in when it's loaded.when the function repeats however, the newly created clip is either not there or i am not referencing it correctly, or there's some problem with the way i'm trying to do this.I don't want to delete the previously attached clip since i'm alpha fading the new one to 100 on top of it.kind of a simple crossfade that way.here's my code:

Code:
startSlides=function(){
this._parent.largePic.createEmptyMovieClip("clipp"+i, 5);
this._parent.largePic["clipp"+i]._alpha=0;[code].....
