Spacing between images

1

Is there a way to modify the code below to make the spacey = a variable + 15 so that the dynamically loaded images can vary in height and be spaced 15px apart? :red:


cliparray = [];
columns = 1;
spacex = 0;
spacey = 420;
function loadXML(loaded) {
 if (loaded) {
  xmlNode = this.firstChild;
  image = [];
  total = xmlNode.childNodes.length;
  for (i=0; i<total; i++) {
   image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
  }
  sload();
  
 } else {
  content = "file not loaded!";
 }
}
this.createEmptyMovieClip("kk", 5029);
kk._x = 0;
kk._y = kk.starty=0;
btn.enabled = false
function drawSquare(clip, depth, colour, x, y, w, h) {
 var mc = clip.createEmptyMovieClip("clip"+depth, depth);
 mc._x = x;
 mc._y = y;
 mc.beginFill(0xcccccc);
 mc.endFill();
 return mc;
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("news.xml");
p = 0;
var ij = 0;
oarray = [];
function sload() {
 for (var i = 0; i<image.length; i++) {
  var clip = drawSquare(kk, i, 0, 0, 0, 575, 330);
  clip._x = (i%columns)*spacex;
  clip._y = Math.floor(i/columns)*spacey;
  if (i%1 == 0) {
   oarray.push(clip._y);
  }
  var clap = clip.createEmptyMovieClip("tt", 1);
  clap._x = 0;
  clap._y = 0;
  cliparray.push(clap);
  clip.pictureValue = i;
  clip.onRelease = function() {
   p = this.pictureValue-1;
   nextImage();
  };
 }
 startload();
}
this.createEmptyMovieClip("checker", 5000);
function checkload() {
 checker.onEnterFrame = function() {
  if (cliparray[ij]._width) {
   delete this.onEnterFrame;
   if (ij<cliparray.length-1) {
    ij++;
    startload();
   }else{btn.enabled = true}
  }
 };
}
function startload() {
 cliparray[ij].loadMovie(image[ij]);
 checkload();
}
