Also good sample at http://blog.devexperience.net/en/12/Send_an_Email_in_CSharp_with_Inline_attachments.aspx

System.Net.Mail.Message Class :

Sample ;

var msg = new System.Net.Mail.Message();
msg.isHTML=true;
msg.Body ="<img src=\"cid:IMG1CONTENT\">";


Attachment mya = new Attachment("file-path-here");
mya.ContentId="IMG1CONTENT";
msg.Attachments.Add(mya);

You can find more details @ http://msdn.microsoft.com/en-us/library/system.net.mail.attachment.aspx

他のヒント

To display the images in email content, one solution is to have an absolute URL. Upload the images to your server and use the abosoluter url as the src attribute value

<img src='http://www.yourdomain.com/youfolder/image.jpg' alt='your image desc'/>

But some email clients will disable external images. So user may need to enable "show images" when propmpted so.
