You can find thumb from Java code using Node#lookup() method.
String IMAGE = getClass().getResource("my-image.png").toExternalForm();
StackPane thumb = (StackPane)slider.lookup(".thumb");
thumb.getChildren().clear();
thumb.getChildren().add(new ImageView(IMAGE));
N.B.: Note you need to call this code after stage.show()
to have lookup working correctly.
