                        that.after("<h3>FACE DETECTED</h3>");
                        that.remove();
                        for (var i = 0; i < faces.length; i++) {
                            $('<div>', {
                                'class':'face',
                                'css': {
                                    'position': 'absolute',
                                    'left':     faces[i].x * faces[i].scaleX + 'px',
                                    'top':      faces[i].y * faces[i].scaleY + 'px',
                                    'width':    faces[i].width  * faces[i].scaleX + 'px',
                                    'height':   faces[i].height * faces[i].scaleY + 'px'
                                }
                            })
                            .insertAfter(this);
                        }
                    },
                    error:function (code, message) {
                        alert('Error: ' + message);
                    }
                });
