I already have a C# windows service that we use internally to monitor a directory on our network and when it detects a change sends off an email using our internal SMTP server to the specified groups of people.

Now I need to embedd an image in that automated email. I understand that I need to create an AlternateView and a Linked Resource and use the Linked Resource's cID in the AlternateView, correct.

What I do not understand is where do I put the image? Should I add it to my service project and set Copy to Output Directory = Copy Always? If so, how would I then access when creating my LinkedResource? Also, where do I put the image on the Server hosting the Service?

Here is what I have so far but it doesn't seem to work. I don't get any errors, that I am aware of, but I do not get an email either. I am guessing it is looking for the image but that I do not have it in the correct location.

// This event is called when an object(file,folder) is created in the srcPath
    void WatcherCreated(object source , FileSystemEventArgs e)
    {
        var folderName = e.Name;
        var folderPath = e.FullPath;

        MailMessage mail = new MailMessage();

        mail.From = new MailAddress("[email protected]");
        mail.To.Add("[email protected]");

        mail.Subject = "New Enrollment for " + folderName;

        AlternateView plainView = AlternateView.CreateAlternateViewFromString("This is the plain text view", null,
                                                                              "text/html");

        AlternateView htmlView =
            AlternateView.CreateAlternateViewFromString("Here is an embedded image. <img src=cid:enrollProcessID>",
                                                        null, "text/html");

        LinkedResource imageResourceLink = new LinkedResource("EnrollmentProcess.jpg")
                                               {ContentId = "enrollProcessID"};

        htmlView.LinkedResources.Add(imageResourceLink);

        mail.AlternateViews.Add(plainView);
        mail.AlternateViews.Add(htmlView);

        var smtp = new SmtpClient("internalSMTP");
        smtp.Send(mail);
    }
