Insert a picture into a header or footer of a word processing doc

Hi team,

I have referred to the link http://msdn.microsoft.com/en-us/library/office/bb497430.aspx to add image part in the word doc

public static void InsertAPicture(string document, string fileName)
{
    using (WordprocessingDocument wordprocessingDocument = 
        WordprocessingDocument.Open(document, true))
    {
        MainDocumentPart mainPart = wordprocessingDocument.MainDocumentPart;

        ImagePart imagePart = mainPart.AddImagePart(ImagePartType.Jpeg);

        using (FileStream stream = new FileStream(fileName, FileMode.Open))
        {
            imagePart.FeedData(stream);
        }

        AddImageToBody(wordprocessingDocument, mainPart.GetIdOfPart(imagePart));
    }
}

private static void AddImageToBody(WordprocessingDocument wordDoc, string relationshipId)
{
    // Define the reference of the image.
    var element =
         new Drawing(
             new DW.Inline(
                 new DW.Extent() { Cx = 990000L, Cy = 792000L },
                 new DW.EffectExtent() { LeftEdge = 0L, TopEdge = 0L, 
                     RightEdge = 0L, BottomEdge = 0L },
                 new DW.DocProperties() { Id = (UInt32Value)1U,

   // Append the reference to body, the element should be in a Run.
   wordDoc.MainDocumentPart.Document.Body.AppendChild(new Paragraph(new Run(element)));
