I am not sure, may be this is expected behaviour, but image in
title area does not fit in dialog. Reason is in following code:
titleImage = new Label(parent, SWT.CENTER);
titleImage.setBackground(background);
titleImage.setImage(JFaceResources.getImage(DLG_IMG_TITLE_BA NNER));
FormData imageData = new FormData();
imageData.top = new FormAttachment(0, verticalSpacing);
imageData.right = new FormAttachment(100, horizontalSpacing);
titleImage.setLayoutData(imageData);
As you can see, right edge of image is right edge of dialog _plus_ spacing.
But this means, that right edge of image is not visible! May be _minus_
required here?

What are the values of verticalSpacing and horizaontalSpacing?
When you attach to the right, and want to offset towards the left (i.e.
move it away from the right edge), you need to make the offset a negative
value. When you attach to the bottom, and want to offset towards the top,
you also need a negative value.
i.e. This will create a border of 5 pixels all the way around:
FormData imageData = new FormData();
imageData.top = new FormAttachment(0, 5);
imageData.left = new FormAttachment(0, 5);
imageData.right = new FormAttachment(100, -5);
imageData.bottom = new FormAttachment(0, -5);
titleImage.setLayoutData(imageData);
Hope this helps... I'm sure that you would know this already. Perhaps a
silly coding mistake!?

Speaking of silly coding mistakes, the line in my example that reads:
imageData.bottom = new FormAttachment(0, -5);
should actually be
imageData.bottom = new FormAttachment(100, -5);

Yes, of course I know, that there should -horizontalSpacing using.
But this is code from JFace TitleAreaDialog, not my.
So, I just sak, may be developer of this code has reason for this.
However, I found another bug in TitleAreaDialog, there is FormData
setting for parent, and parent is not in FormLayout, so I can suggest,
that problem with image is also bug...
Well, I add bug 41172.
