[F8] 1 button/1 click 2 jpg into seperate MC's

Hey guys i am trying to figure out how to load 2 or 3 jpg's externally, when I click on 1 button. I have 3 different MC's 1 big and 2 small. This is the AS I am using. Thanks for you help.

stop();
imgbtn1.onRelease = function() {
infoField._visible = true;
startLoading("dsc_3715.jpg");
};
function startLoading(whichImage) {
loadMovie(whichImage, "imageLoader");
_root.onEnterFrame = function() {
infoLoaded = imageLoader.getBytesLoaded();
infoTotal = imageLoader.getBytesTotal();
percentage = Math.floor(infoLoaded/infoTotal*100);
infoField.text = percentage+"%";
if (percentage>=100) {
delete this.onEnterFrame;
infoField._visible = false;
}
};
}
