title: C# sending mails with images inline using SmtpClient
body: <p>SmtpClient() allows you to add attachments to your mails, but what if you wanna make an image appear when the mail opens, instead of attaching it?</p>
  
  <p>As I remember, it can be done with about 4 lines of code, but I don't remember how and I can't find it on the MSDN site.</p>
  
  <p>EDIT: I'm not using a website or anything, not even an IP address. The image(s) are located on a harddrive. When sent, they should be part of the mail. So, I guess I might wanna use an  tag... but I'm not too sure, since my computer isn't broadcasting.</p>
