title: Show figure in input dialog box matlab
body: <p>i would like to know how i can add a figure to my inputdlg() in matlab. I would like to show a small figure i created to help with filling in the input.
  This is my input dialog i have.</p>
  
  <pre><code>    prompt       = {'Length:'};
      dlg_title    = 'Straight Duct specs';
      num_lines    = 1;
      SDelements   = {'0'};
      Straightduct = inputdlg(prompt,dlg_title,num_lines,SDelements);
  </code></pre>
  
  <p>Perhaps some one can show me the way?
  cheers</p>
