Loop a loader

there are 10 images, and for some strange reason this function will only load one image into the first polaroid.img_container, and will not load the rest in the for loop. I believe it has something to do with the URLRequest, but searching has become inconclusive. Any help would be appreciated!

function Test() {
var count=0;
for( var i:int = 0; i<totalRows; i++){
for( var j:int=0; j<totalColumns; j++){
obj[count] = new polaroid();
this.addChild(obj[count]);
obj[count].x=j130;
obj[count].y=i
130;
ldr[count] = new Loader();
ldr[count].mask = obj[count].img_container;
var url:String = “http://192.168.15.100/patriciaferia.com/images/thumb-"+(count+1)+".jpg”;
var urlReq = new URLRequest(url);
ldr[count].load(urlReq);
addChild(ldr[count]);
obj[count].addEventListener(MouseEvent.CLICK, dropAndSplash);
count++;
}
}
}
