Set max width/heigth for dynamicly called MC

[marcelcolt]

I couldn't get it to work.
Do i use it like this (Sorry, my syntax sucks):

    createEmptyMovieClip("imagecontainermedium", getNextHighestDepth());
    // set the alpha to not see the picture loading...
    imagecontainermedium._alpha = 0;
    imagecontainermedium.loadMovie("photo/images/1.jpg");
		if (imagecontainermedium._xscale >= 317)
     		{imagecontainermedium._width=316}
		if (imagecontainermedium._yscale >= 317)
     		{imagecontainermedium._height=316};
    onEnterFrame = function(){
        if(imagecontainermedium.getBytesLoaded() >= imagecontainermedium.getBytesTotal() && imagecontainermedium.getBytesLoaded() > 0){
            imagecontainermedium._x  = 320 - imagecontainermedium._width/2; 
            imagecontainermedium._y  = 67 - imagecontainermedium._height/2;
            delete onEnterFrame;
            imagecontainermedium._alpha = 100; 
        }
    };
