Okay let me explain that a little better.
I have a mvc project with a html page and some images and have set up a smtp server to send an email.
When i debug the webpage i get the localhost url. (Localhost:51180)
The Email i try to send looks like this: (simplified version):

```
<html>
<body>
<img alt="img" src="https://www.google.com/images/srpr/logo11w.png" />*Working
<img alt='img' src='localhost:51180/Images/img.png'/> *not working
</body>
</html>

```

My problem is that the second pic doesn't work. (if i copy past the url in my web browser while the project is running i can see its the right path). Is it because the website is running local on my computer and the email cant get access to it? or something else? 
Thanks in Advance!
