Over riding coordinates

Hello,
I have a script that when you press button 1-6 it loads external image and external text
when the movie plays button1 is active
what i need to know is i want button1 images in a different position,
as the images position is defined when the empty movieclip is created
even if i individually set each image position is ok,


//Create empty movieclip
_root.createEmptyMovieClip("imageHolder_mc", 1);
_root.imageHolder_mc._x = 120;
_root.imageHolder_mc._y = 0;

//Load Person1
button1.onRelease = function() {
  loadVariablesNum("person1.txt", 0);
  infoField._visible = true;
  startLoading("person1.jpg");
};
//Load Person2
button2.onRelease = function() {
 infoField._visible = true;
 startLoading("person2.jpg");
 loadVariablesNum("person2.txt", 0);
};
//Load Person3
button3.onRelease = function() {
 infoField._visible = true;
 startLoading("person3.jpg");
 loadVariablesNum("person3.txt", 0);
};
//Load Person4
button4.onRelease = function() {
 infoField._visible = true;
 startLoading("person4.jpg");
 loadVariablesNum("person4.txt", 0);
};
//Load Person5
button5.onRelease = function() {
 infoField._visible = true;
 startLoading("person5.jpg");
 loadVariablesNum("person5.txt", 0);
};
//Load Person6
button6.onRelease = function() {
 infoField._visible = true;
 startLoading("person6.jpg");
 loadVariablesNum("person6.txt", 0);
};
button1.onRelease ();

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