Hey fellow programmers

       I am accessing word 2003 documents through vba. I wanted to programmatically insert / delete watermarks in an already existing document and align the text accordingly; here is the code I got from a macro. I dint get some function details from here could you people help me out


---------------------------Macro code-------------------------

    ActiveDocument.Sections(1).Range.Select
    ActiveWindow.ActivePane.View.SeekView = wdSeekCurrentPageHeader
    Selection.HeaderFooter.Shapes.AddPicture(FileName: = _
        "D:\Documents and Settings\Administrator\Desktop\images\images1.jpg" , _
        LinkToFile:=False, SaveWithDocument:=True).Select
    Selection.ShapeRange.Name = "WordPictureWatermark1"
    Selection.ShapeRange.PictureFormat.Brightness = 0.5
    Selection.ShapeRange.PictureFormat.Contrast = 0.5
    Selection.ShapeRange.LockAspectRatio = True
    Selection.ShapeRange.Height = InchesToPoints(9.86) <---- how in the world did word know the size of the picture in inches
    Selection.ShapeRange.Width = InchesToPoints(7.71)
    Selection.ShapeRange.WrapFormat.AllowOverlap = True
    Selection.ShapeRange.WrapFormat.Side = wdWrapNone
    Selection.ShapeRange.WrapFormat.Type = 3
    Selection.ShapeRange.RelativeHorizontalPosition = _
        wdRelativeVerticalPositionMargin
    Selection.ShapeRange.RelativeVerticalPosition = _
        wdRelativeVerticalPositionMargin
    Selection.ShapeRange.Left = wdShapeCenter
    Selection.ShapeRange.Top = wdShapeCenter
    ActiveWindow.ActivePane.View.SeekView = wdSeekMainDocument

-----------------------------end------------------------------
