Reattach an Image after removeFromParent in GWT

attach an Image after you have called removeFromParent in GWT?

The Image was created from an UiBinder e.g.

<g:HTMLPanel>
    <g:Image ui:field="myImage"/>
</g:HTMLPanel>

public class Testing extends Composite {
  interface MyUiBinder extends UiBinder<Widget, Testing> {}
  private static MyUiBinder uiBinder = GWT.create(MyUiBinder.class);
  @UiField Image myImage;
  public Testing() {
    initWidget(uiBinder.createAndBindUi(this));
  }
  public void remove() {
    myImage.removeFromParent();
  }
  public void add() {
    ...
  }

Well, I suppose you could add a field referencing your container panel:

<g:HTMLPanel ui:field="imgPanel">
    <g:Image ui:field="myImage"/>
</g:HTMLPanel>

you could then go:

imgPanel.add(myImage);

Instead of remove the image, you can just hide the image :

public void remove() {
  myImage.setVisible(false);
}
public void add() {
  myImage.setVisible(true);
}

Add and remove from the DOM is expensive for the browser.
