Email with Embedded image in ASP.Net

We can embed image in email body using LinkedResource class and AlternateView class that is packed with System.Net.Mail namespace. We can achieve this by making the message as HTML
.
MailMessage mail = new MailMessage();
            mail.To.Add("xxx@gmail.com");
            mail.From = new MailAddress("xxxx@gmail.com");
            mail.Subject = "Test with Image";
            string Body = "<b>Welcome to popfly!!</b><br><img alt=\"\"
             hspace=0 src=\"cid:imageId\" align=baseline border=0 >";

            AlternateView htmlView = AlternateView.CreateAlternateViewFromString(Body, null, "text/html");
            LinkedResource imagelink = new LinkedResource(Server.MapPath(".") +
                                                                                 @"\popfly.JPG", "image/jpeg");
            imagelink.ContentId = "imageId";
            imagelink.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
            htmlView.LinkedResources.Add(imagelink);

            mail.AlternateViews.Add(htmlView);
            SmtpClient smtp = new SmtpClient();
            smtp.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
            smtp.Send(mail);
