How can I do it works for Hotmail users ?

C#

MailMessage MsgTorp = new MailMessage(pOrigem, pDestino, pTitulo, pTexto);
ContentType mimeType = new System.Net.Mime.ContentType("text/html");
AlternateView alternate = AlternateView.CreateAlternateViewFromString(MsgTexto, mimeType);

LinkedResource FotoUser = new LinkedResource(pFoto);
FotoUser.ContentId = "FotoUserTorpedo";
FotoUser.TransferEncoding = TransferEncoding.Base64;
alternate.LinkedResources.Add( FotoUser );

Attachment attach = new Attachment(pFoto);
MsgTorp.Attachments.Add(attach);

MsgTorp.IsBodyHtml = true;
MsgTorp.AlternateViews.Add(alternate);

SmtpClient SmtpCliente = new SmtpClient(); //pServer);
SmtpCliente.Send(MsgTorp);

Thanks,

Guilherme

I am not sure if this is the correct way, but you can embed images in the IMG tag's SRC attribute (i.e., you put the actual image data in the SRC attribute, rather than the URL to the image data). See here: Data URI Image Extractor.

this is your problem:

ContentType mimeType = new System.Net.Mime.ContentType("text/html");

you need to tell hotmail what type you are embedding.

this works, but you'll need to add some error catching:

using Microsoft.Win32;
RegistryKey key = Registry.ClassesRoot.OpenSubKey(extension);
string contentType = key.GetValue("Content Type").ToString();
