Remove moviecliploader

Hello
I’m new here and it’s like 3hrs that i search for an answer for my problem , so I decide to put a message on this forum and I hope that someone can help me!!

I use the tutorial : «Reusable Preloader Using MovieClipLoader» for loading my image on my portfolio website. I have 4 scenes (intro, design, illustration and CV) , in the design scene i begin a short anim with text and image and i invite people to click for watching my work. It’s where i use the tutorial for showing my work. I put the empty movie clip container to show my work. I have 15 buttons who all load in the same container. In this scene, i have a button for go back to intro or go to illustration, CV. When i click on it, i have a short animation and i change of scene.

My problem is when a click after viewing and loading my work, it’s stay in place. The container continue to show me the last picture that i load. It’s not cool!!

How can i remove the container, to remove it from the scene after view my picture???
Do i have to put another code after this below?? Or on another key frame??

Thanks for your help , i’m not a pro and i really need help!!

This the code that i use (from the tutorial) :
MovieClip.prototype.fadeIn = function() {
this.onEnterFrame = function() {
if (this._alpha<100) {
this._alpha += 10;
} else {
delete this.onEnterFrame;
}
};
};
bar._visible = false;
border._visible = false;
var empty = this.createEmptyMovieClip(“container”, “600”);
empty._x = 100;
empty._y = 40;
my_mc = new MovieClipLoader();
preload = new Object();
my_mc.addListener(preload);
preload.onLoadStart = function(targetMC) {
trace("started loading “+targetMC);
container._alpha = 0;
bar._visible = true;
border._visible = true;
pText._visible = true;
};
preload.onLoadProgress = function(targetMC, lBytes, tBytes) {
bar._width = (lBytes/tBytes)100;
pText.text = "% "+Math.round((lBytes/tBytes)100);
};
preload.onLoadComplete = function(targetMC) {
container.fadeIn();
border._visible = false;
bar._visible = false;
dText.visible = false;
trace(targetMC+" finished");
};
//default image
my_mc.loadClip("Aff
**.jpg”, “container”);
//buttons
button1.onPress = function() {
my_mc.loadClip(“Jackalope.swf”, “container”);
};
button2.onPress = function() {
my_mc.loadClip(“Aff_Jackalope.jpg”, “container”);
};
button3.onPress = function() {
my_mc.loadClip(“Aff_Jackalope.jpg”, “container”);
};
button4.onPress = function() {
my_mc.loadClip(“Aff_Jackalope.jpg”, “container”);
};

};

my_mc.loadClip(“Aff_Jackalope.jpg”, “container”);
};
button8.onPress = function() {
my_mc.loadClip(“Aff_Jackalope.jpg”, “container”);
};
button9.onPress = function() {
