I'm writing a program that sends emails to users with multiple images (charts) embedded in the Email message body (HTML).
When I tried the sample located here..which worked well when I have to embed only one image http://www.systemnetmail.com/faq/4.4.aspx.
But, when i tried to embed multiple images using the below code, none of the images are being embedded , instead they are sent as attachments.
public MailMessage MailMessage(Metric metric, DateTime date)
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress("[email protected]", "User1");
msg.To.Add(new MailAddress("[email protected]"));
msg.Subject = "Trend for metric: " + metric.Name;
msg.IsBodyHtml = true;
// Generate the charts for the given metric
var charts = this.GenerateCharts(metric, date);
int i = 0;
string htmlBody = "<html><body>";
List<LinkedResource> resources = new List<LinkedResource>();
foreach (var chart in charts)
{
string imageTag = string.Format("<img src=cid:chart{0} /><br>", i);
htmlBody += imageTag;
LinkedResource graph = new LinkedResource(chart.Value, "image/jpeg");
graph.ContentId = "chart" + i;
resources.Add(graph);
i++;
}
htmlBody += "</body></html>";
// Alternate view for embedded images
AlternateView avText = AlternateView.CreateAlternateViewFromString(metric.Name, null, MediaTypeNames.Text.Html);
AlternateView avImages = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
// Add all the images as linked resources
resources.ForEach(x => avImages.LinkedResources.Add(x));
// Add the views for image
msg.AlternateViews.Add(avText);
msg.AlternateViews.Add(avImages);
return msg;
}
Any clues as what I'm missing? I checked the .htm file which is also sent as attachment with the email, and html source looks as follows:
<html>><body><img src=cid:chart0 /><br><img src=cid:chart1 /><br><img src=cid:chart2/><br><img src=cid:chart3 /><br><img src=cid:chart4 /><br></body></html>
So the Q is how to send multiple images in the html body , not as attachment.

Select Insert > Pictures. Browse your computer or online file locations for the picture you want to insert. Select the picture, then select Insert.
The other way to embed images in E-mail when using System.Net.Mail is
Attach image from local drive to email and assign a contentID to it and later use this contentID in the image URL.
This can be done by:
var contentID = "Image";
var inlineLogo = new Attachment(@"C:\Desktop\Image.jpg");
inlineLogo.ContentId = contentID;
inlineLogo.ContentDisposition.Inline = true;
inlineLogo.ContentDisposition.DispositionType = DispositionTypeNames.Inline;
msg.IsBodyHtml = true;
msg.Attachments.Add(inlineLogo);
msg.Body = "<htm><body> <img src=\"cid:" + contentID + "\"> </body></html>";
