Call static content

[Peter Penzov]

I have this code from JavaFX application:

private static final ImageView ncpic;
    static {
        ncpic = new
ImageView(TabContent.class.getResource("/images/6.jpg").toExternalForm());
    }

I noticed that I can use this picture only once. When I use it twice the
scene where I call it it's empty. How I can use this picture twice or more
times? Maybe this is caused by the static java method which I call to
display the picture?

quick example:

public class TabContent {

    private static final ImageView ncpic;
        static {
            ncpic = new
ImageView(TabContent.class.getResource("/images/6.jpg").toExternalForm());
        }

        private static StackPane generalConfiguration() {

            StackPane stack = new StackPane();
            stack.getChildren().addAll(ncpic);   // Add the picture
and the Label
            return stack;
        }}

I use it this way: TabContent.generalConfiguration() And second time in
different Java Class.
