Bug 230071 Snippet223 requires an image
I just tried to run Snippet223 and it fails trying to acquire the 'eclipse.png' image...all the other snippets I've seen are self-contained (one of their best features...;-).

layout.marginLeft = layout.marginTop = layout.marginRight = layout.marginBottom = 10;
	layout.verticalSpacing = 10;
	composite.setLayout(layout);	
	Label label = new Label (composite, SWT.NONE);
	label.setImage(display.getSystemImage(SWT.ICON_ERROR));
	label = new Label (composite, SWT.NONE);
	label.setText("SWT.ICON_ERROR");
	label = new Label (composite, SWT.NONE);
	label.setImage(display.getSystemImage(SWT.ICON_INFORMATION));

	item1.setControl(composite);
	item1.setImage(image);
