Dynamic loading of images not working anymore

hello folks

this image ‘gallery’ worked already but now i added this loadImgs part with the loadvars and now it doesn’t load any image anymore!

if i trace the thumb var i get the list of the images which should be loaded!

   stop();
    
    loadImgs = new LoadVars();
    loadImgs.load("http://oks.ok/getIntroImages");
    loadImgs.onLoad = function() {
    	is = this.iurls;
    	imgs = is.split(";");
    
    //this.imgs = ['http://oks.ok/cover.jpg','http://oks.ok/cover.jpg'];
    
    var x = 0;
    var y = 0;
    var fadeSpeed = 30;
    var fadeMax = 90;
    
    for (var i = 0; i < imgs.length; i++) {	
    	var t = this.createEmptyMovieClip("thumbnail" + i, i);
    	var c = t.createEmptyMovieClip("picHolder", 0);
    	var thumb = imgs*;
    	c.loadMovie(thumb);
    
    	t._x = x + (80 * i);
    	t._y = y;
    	t._alpha = 0;
    	t.canfade = false;
    	t.num = i;
    	t.onEnterFrame = function() {
    		if (this.canfade || !this.num) {
    			if (this._alpha<=fadeMax) {
    				this._alpha += fadeSpeed;
    			} else {
   			 this._parent["thumbnail"+(this.num+1)].canfade = true;
    			}
    		}
    	};
    }
    
    };
      

any ideas? please help me!!!

  thanks in advanace!
