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.
Here is what I have so far
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(
"<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
@"<img src=""cid:{0}"" />", inline.ContentId);
mail.IsBodyHtml = true;
mail.Attachments.Add(att);
We all have our preferred coding styles. This is what I did:
var pictures = new[]
{
new { id = Guid.NewGuid(), type = "image/jpeg", tag = "justme", path = @"C:\Pictures\JustMe.jpg" },
new { id = Guid.NewGuid(), type = "image/jpeg", tag = "justme-bw", path = @"C:\Pictures\JustMe-BW.jpg" }
}.ToList();
var content = $@"
<style type=""text/css"">
body {{ font-family: Arial; font-size: 10pt; }}
</style>
<body>
<h4>{DateTime.Now:dddd, MMMM d, yyyy h:mm:ss tt}</h4>
<p>Some pictures</p>
<div>
<p>Color Picture</p>
<img src=cid:{{justme}} />
</div>
<div>
<p>Black and White Picture</p>
<img src=cid:{{justme-bw}} />
</div>
<div>
<p>Color Picture repeated</p>
<img src=cid:{{justme}} />
</div>
</body>
";
// Update content with picture guid
pictures.ForEach(p => content = content.Replace($"{{{p.tag}}}", $"{p.id}"));
// Create Alternate View
var view = AlternateView.CreateAlternateViewFromString(content, Encoding.UTF8, MediaTypeNames.Text.Html);
// Add the resources
pictures.ForEach(p => view.LinkedResources.Add(new LinkedResource(p.path, p.type) { ContentId = p.id.ToString() }));
using (var client = new SmtpClient()) // Set properties as needed or use config file
using (MailMessage message = new MailMessage()
{
IsBodyHtml = true,
BodyEncoding = Encoding.UTF8,
Subject = "Picture Email",
SubjectEncoding = Encoding.UTF8,
})
{
message.AlternateViews.Add(view);
message.From = new MailAddress("[email protected]");
message.To.Add(new MailAddress("[email protected]"));
client.Send(message);
}
Some minimal c# code to embed an image, can be:
MailMessage mailWithImg = GetMailWithImg();
MySMTPClient.Send(mailWithImg); //* Set up your SMTPClient before!
private MailMessage GetMailWithImg() {
MailMessage mail = new MailMessage();
mail.IsBodyHtml = true;
mail.AlternateViews.Add(GetEmbeddedImage("c:/image.png"));
mail.From = new MailAddress("yourAddress@yourDomain");
mail.To.Add("recipient@hisDomain");
mail.Subject = "yourSubject";
return mail;
}
private AlternateView GetEmbeddedImage(String filePath) {
LinkedResource res = new LinkedResource(filePath);
res.ContentId = Guid.NewGuid().ToString();
string htmlBody = @"<img src='cid:" + res.ContentId + @"'/>";
AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(res);
return alternateView;
}
sending 2 images vb.net code convert for C# online converter.

In addition to the comments above, I have the following additional comments:
"cid:att-001" this does NOT work on iPhone (late 2016 patch level), rather use pure alpha numeric "cid:att-001" -> "cid:att001"As an aside: Outlook (even Office 2015) rendering (still the clear majority for business users) requires the use of TABLE TR TD style HTML, as it does not fully support the HTML box model.
You need to add the LinkedResource into an AlternateView
AlternateView alternateView = AlternateView.CreateAlternateViewFromString("<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
@"<img src=""cid:{0}"" />", null, "text/html");
alternateView.LinkedResources.Add(inline);
mail.AlternateViews.Add(alternateView);
The other solution is attaching the image as attachment and then referencing it html code using cid. HTML Code:
<html>
<head>
</head>
<body>
<img width=100 height=100 id=""1"" src=""cid:Logo.jpg"">
</body>
</html>
C# Code:
EmailMessage email = new EmailMessage(service);
email.Subject = "Email with Image";
email.Body = new MessageBody(BodyType.HTML, html);
email.ToRecipients.Add("[email protected]");
string file = @"C:\Users\acv\Pictures\Logo.jpg";
email.Attachments.AddFileAttachment("Logo.jpg", file);
email.Attachments[0].IsInline = true;
email.Attachments[0].ContentId = "Logo.jpg";
email.SendAndSaveCopy();

}
An even more minimalistic example:
var linkedResource = new LinkedResource(@"C:\Image.jpg", MediaTypeNames.Image.Jpeg);
// My mail provider would not accept an email with only an image, adding hello so that the content looks less suspicious.
var htmlBody = $"hello<img src=\"cid:{linkedResource.ContentId}\"/>";
var alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(linkedResource);
var mailMessage = new MailMessage
{
From = new MailAddress("[email protected]"),
To = { "[email protected]" },
Subject = "yourSubject",
AlternateViews = { alternateView }
};
var smtpClient = new SmtpClient();
smtpClient.Send(mailMessage);
I added the complete code below to display images in Gmail,Thunderbird and other email clients :
MailMessage mailWithImg = getMailWithImg();
MySMTPClient.Send(mailWithImg); //* Set up your SMTPClient before!
private MailMessage getMailWithImg()
{
MailMessage mail = new MailMessage();
mail.IsBodyHtml = true;
mail.AlternateViews.Add(getEmbeddedImage("c:/image.png"));
mail.From = new MailAddress("yourAddress@yourDomain");
mail.To.Add("recipient@hisDomain");
mail.Subject = "yourSubject";
return mail;
}
private AlternateView getEmbeddedImage(String filePath)
{
// below line was corrected to include the mediatype so it displays in all
// mail clients. previous solution only displays in Gmail the inline images
LinkedResource res = new LinkedResource(filePath, MediaTypeNames.Image.Jpeg);
res.ContentId = Guid.NewGuid().ToString();
string htmlBody = @"<img src='cid:" + res.ContentId + @"'/>";
AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlBody,
null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(res);
return alternateView;
}
Try This.
