title: Send inline image in email
body: <p>Having an issue sending an image via email as an embedded image in the body.
  The image file shows as an attachment which is ok but the inline image portion just shows as a red x.</p>
  
  <p>Here is what I have so far</p>
  
  <pre><code>LinkedResource inline = new LinkedResource(filePath);
  inline.ContentId = Guid.NewGuid().ToString();
  MailMessage mail = new MailMessage();
  Attachment att = new Attachment(filePath);
  att.ContentDisposition.Inline = true;
  mail.From = from_email;
  mail.To.Add(data.email);
  mail.Subject = "Client: " + data.client_id + " Has Sent You A Screenshot";
  mail.Body = String.Format(
      "&lt;h3&gt;Client: " + data.client_id + " Has Sent You A Screenshot&lt;/h3&gt;" +
      @"&lt;img src=""cid:{0}"" /&gt;", inline.ContentId);
  
  mail.IsBodyHtml = true;
  mail.Attachments.Add(att);
  </code></pre>
