Loading one image at a time with for loop?

Hi, I have a function where i load some images from an XML file. The function builds up a pattern with boxes in lines of 4, and for each Image-tag in the XML file, it creates a new box in that pattern and loads an image into it. The problem is that as the code is written now, all the images are loaded and displayed at once.

I would want the function to load one image at a time, so that image box is displayed, and then the next one, and next one, and so on. Is it possible with my function? What should I change? And also, is there a better way you could suggest to make that pattern that the boxes form? As you see now, it’s a lot of code counting each row of 4 boxes.

I greatly appreciate any help! this is the function below:

//Loading work objects from XML
var home:MovieClip = this;

xFirst = 0;
yFirst = 0;
yStep = 131;
xPlace = 0;
yPlace = 0;

var numOfItems:Number;

function loadXML(loaded) {
    if (loaded) {
    var nodes = this.firstChild.childNodes;
    numOfItems = nodes.length;
    var myArr = new Array();
        for(var i=0;i<numOfItems;i++) {
            if (i <= 4) {
                xPlace = xFirst + (181*i);
                yPlace = yFirst;
            }
            else if ((i >= 5) && (i <= 9)) {
                xPlace = xFirst + ((181)*(i-5));
                yPlace = yFirst + (yStep*1);
            }
            else if ((i >= 10) && (i <= 14)) {
                xPlace = xFirst + ((181)*(i-10));
                yPlace = yFirst + (yStep*2);
            }
            else if ((i >= 15) && (i <= 19)) {
                xPlace = xFirst + ((181)*(i-15));
                yPlace = yFirst + (yStep*3);
            }
            else if ((i >= 20) && (i <= 24)) {
