container_mc._x = _root.gallery_x;
container_mc._y = _root.gallery_y;
var clipLoader = new MovieClipLoader();
var preloader = new Object();
clipLoader.addListener(preloader);
for (i=0; i<_root.myImagesTotal; i++) { 
thumbURL = myImages*.attributes.thumb_url; 
myThumb_mc = container_mc.createEmptyMovieClip(i, container_mc.getNextHighestDepth() );
myThumb_mc._y = _root.thumb_height*i;
clipLoader.loadClip("thumbs/"+thumbURL,myThumb_mc);
}
