title: Create a document with python-docx where the header only appears on the first page
body: <p>I am using python-docx to create a word document from scratch and I have managed to add an image header to the document. However the header image is repeated over all the pages and I do not fully understand how <code>sections</code> and <code>header.is_linked_to_previous</code> works to be able to figure out how to only have the header on the first page.</p>
  
  <pre><code>document = Document()
  header = document.sections[0].header
  htable = header.add_table(1, 1, Inches(6))
  htab_cells = htable.rows[0].cells
  ht0 = htab_cells[0].add_paragraph()
  kh = ht0.add_run()
  kh.add_picture('BothHeaderLogos.png', width=Inches(5.6))
  current_section = document.sections[-1]
  new_section = document.add_section(WD_SECTION.ODD_PAGE)
  document.add_heading("Sequence Summary", level=1)
  header.is_linked_to_previous = False
  </code></pre>
