title: python + excel: how to programmatically insert picture into comment
body: <p>I need to insert a picture into an excel cell comment box. Example of what I mean <a href="http://www.computergaga.com/blog/insert-a-picture-into-a-comment/" rel="nofollow noreferrer">here</a>.</p>
  
  <p>Is there a way to do this with an existing python library?</p>
  
  <p>I have looked at both <a href="https://openpyxl.readthedocs.io/en/latest/comments.html" rel="nofollow noreferrer">openpyxl</a> and <a href="http://xlsxwriter.readthedocs.io/working_with_cell_comments.html#cell-comments" rel="nofollow noreferrer">xlsxwriter</a> docs - it seems they just allow the creation of text comments.  </p>
  
  <p>Xlsx writer allows you to change the background color of a comment box, but it appears there is no solution for inserting a picture.</p>
