title: pandoc markdown to pdf showing file names next to image
body: <p>When I convert a markdown file to pdf using pandoc, any image links such as </p>
  
  <pre><code>![](path/to/name_of_file)
  </code></pre>
  
  <p>the pdf includes the image but has a "Figure n:" under the image. How can I suppress this behaviour?</p>
  
  <p>Secondly, if I include a header using </p>
  
  <pre><code>\usepackage{graphicx}
  \usepackage{fancyhdr}
  \pagestyle{fancy}
  \lhead{\includegraphics[width=3cm]{/Users/pdd/Documents/DATA/Work/Logo/DCM logo email image.jpg}}
  </code></pre>
  
  <p>in my template.latex file, the pdf includes the image but displays the image name before the image, inserts a horizontal line under the image and places "Heading 1" on the right of the page as an additional header. Again, how can I suppress this behaviour?</p>
  
  <p>Many Thanks</p>
