var imageViewer:MovieClip = attachMovie("imageviewer", "imageView", getNextHighestDepth());
            imageView._x = Stage.width/2-imageViewer._width/2-10;
            imageView._y = Stage.height/2-imageViewer._height/2;
            //close button
            this.createTextField("closeWindow_txt", getNextHighestDepth(), 595, 108, 200, 100);

            trace(closeWindow_txt.text);
            //end close button
            //loadmovie

            this.thumbInfo = this.imageView.createEmptyMovieClip("thumbinfo", getNextHighestDepth());
            this.thumbInfo.loadMovie(this.picHolder);
            //trace("after movie");
