Usually when we are sending images in an email, we place the...
<img src="" alt="" />
...tag in the HTML email body and the 'src' of the image tag points to the HTTP URL of the image. To get this HTTP URL, the image has to be hosted somewhere,

LinkedResource LinkedImage = new LinkedResource(@"J:\My Documents\Advika1.jpg");
LinkedImage.ContentId = "MyPic";
LinkedImage.ContentType = new ContentType(MediaTypeNames.Image.Jpeg);
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(
"You should see image next to this line. <img src=cid:MyPic>",
SmtpClient smtp = new SmtpClient("220.127.116.11", 25);
catch (SmtpException ex)
