[Flash 8] help with loader_Mc an dynamically loading jpgs

Hello, I am trying to dynamically load .jpgs into an Mc, and have this code on the loader clip

var loader:MovieClipLoader = new MovieClipLoader();
loader.addListener(this);

function onLoadInit(_mc:MovieClip) {
    gotoAndPlay(2);
};

loader.loadClip("img/fan.jpg", _root.jpg_holder);

it works fine but i want to make it so it works for all the .jpgs i am trying to load not just “img/fan.jpg”. is there someway to do this easily? i´m sure there´s a simple solution but just has´nt hit me yet.

cheers if you can help.
