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...;-).
examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet223.java
Display display = new Display ();
	Shell shell = new Shell (display);
	shell.setLayout(new FillLayout());
	shell.setText("ExpandBar Example");
	ExpandBar bar = new ExpandBar (shell, SWT.V_SCROLL);
	Image image = new Image(display, Snippet223.class.getResourceAsStream("eclipse.png")); 
	
	
	Composite composite = new Composite (bar, SWT.NONE);
	GridLayout layout = new GridLayout ();
	layout.marginLeft = layout.marginTop = layout.marginRight = layout.marginBottom = 10;
	layout.verticalSpacing = 10;
	composite.setLayout(layout);
	Button button = new Button (composite, SWT.PUSH);
	button.setText("SWT.PUSH");
	button = new Button (composite, SWT.RADIO);
	button.setText("SWT.RADIO");
	button = new Button (composite, SWT.CHECK);
	button.setText("SWT.CHECK");
	button = new Button (composite, SWT.TOGGLE);
	button.setText("SWT.TOGGLE");
	ExpandItem item0 = new ExpandItem (bar, SWT.NONE, 0);
	item0.setText("What is your favorite button");
	item0.setHeight(composite.computeSize(SWT.DEFAULT, SWT.DEFAULT).y);
	item0.setControl(composite);
	item0.setImage(image);
	
	
	composite = new Composite (bar, SWT.NONE);
	layout = new GridLayout (2, false);
