title: Laravel display image in email
body: <p>I am sending an email to my users of something they've submitted to confirm.
  The users can upload images so I want to display these images in the email overview.</p>
  
  <p>The images are being saved and I save the path in my database. Only when I try to display the images I get <code>src=(unknown)</code> when I spectate in my email client.</p>
  
  <p>This is how I print out the images:</p>
  
  <pre><code>&lt;img class="thumbnail" src="&lt;?php echo '/storage/' . $filename ?&gt;" /&gt;
  </code></pre>
  
  <p>$filename is passed as data from my mailable class when I just echo the $filename it is the right data from my database so there is no issue there.</p>
