Making mc loader URL?

Hello people,

I have 4 small invisible buttons on one timeline. Each of these small buttons loads an external jpg into a movie clip container.

I want each one of these external jpgs that load into the same mc container to go to a new web page. I am trying to do this with a invisible button that goes over where the external jpgs show up. What is the best way of doing this?

I can put up the action script if you like.
Thanks for your help.

Please post your script.

Here is the AS2 from the smaller buttons. I want the larger invisible button that is on top of the external jpg to do a getURL.

Actionscript Code:

on (rollOver) {
    this.small1.small1A.glowMC.gotoAndPlay("playglow");
    this.small1.small1A.yellowbox.gotoAndPlay("startyellow");
    this.small1.gotoAndPlay("startdown");
}
on (rollOut) {
    this.small1.small1A.glowMC.gotoAndPlay("endglow");
    this.small1.small1A.yellowbox.gotoAndPlay("endyellow");
    this.small1.gotoAndPlay("startup");
    this.small1.smallA.yellowbox.gotoAndPlay("boxsmall");


}
on (press) {
    this.small1.small1A.yellowbox.gotoAndStop("pushyellow");
    


}

on (release) {
    this.small1.small1A.yellowbox.gotoAndPlay("pushyellow");
    var mcHolder:MovieClip = createEmptyMovieClip("mcHolder", getNextHighestDepth());
    var mcLoader:MovieClipLoader = new MovieClipLoader();
    mcLoader.addListener(this);

    (mcLoader.loadClip("externalpic.jpg", mcHolder));


}
