title: Invalid temp images directory in chart handler configuration
body: <p>I am using highchart and I am getting this error only when I run my website on IIS server in intranet network. Instead it works fine in the development server (visual studio 2012)</p>
  
  <blockquote>
    <p>Invalid temp images directory in chart handler configuration
    [c:\TempImageFiles]. Please edit the web.config file. The
    CharImageHandler key, Dir value must point to a valid directory. The
    directory is required for temporary image storage when storage mode
    equals file system.</p>
