Embedding PNG images into an email in WPF

I am having issues getting a PNG to render as an embedded image in an email. All I am trying to do is embed a company logo in the bottom of an email.

The image is a resource in my project.

Here is code I am using to generate the email body text and alternate views:

string body =
    @"<html><body><b>Please do not respond to this message</b><br/><br/>" +
     "<img src='cid:companyLogo' width='100px'/></body></html>";

Bitmap logo = new Bitmap(Properties.Resources.logo_dark_background);
MemoryStream logoStream = new MemoryStream();
logo.Save(logoStream, ImageFormat.Jpeg);
LinkedResource companyLogo = new LinkedResource(logoStream);
companyLogo.ContentId = "companyLogo";
companyLogo.ContentType = new ContentType("image/jpg");
AlternateView av = AlternateView.CreateAlternateViewFromString(
    body, null, MediaTypeNames.Text.Html);
av.LinkedResources.Add(companyLogo);
message.AlternateViews.Add(av);

Please note that 'message' is a MailMessage object created earlier on.

The problem is that your stream's position is at the end of the stream after saving the logo.

Immediately after the logo.Save() call, you can set logoStream.Position = 0 to reset it to the beginning.

Also don't forget to dispose of your stream, most likely in a using statement.
