title: Email Readership Image shows in outlook mail as Cross 'x'
body: <p>I am embedding an image in my html mail like this</p>
  
  <pre><code>&lt;img src="foo.jpg" width="0" height="0" 
       style="display: none; margin: 0; border: 0; padding: 0;" /&gt;
  </code></pre>
  
  <p>When the mail is opened in outlook, the image shows as </p>
  
  <p><a href="https://i.stack.imgur.com/m9rP9.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/m9rP9.jpg" alt="enter image description here"></a></p>
  
  <p>But, when the source of mail is saved as html, it is not shown as <code>height</code>, <code>width</code> is <code>0</code> and <code>display</code> is <code>none</code>.</p>
  
  <p>Why is this so? Am I missing something?</p>
  
  <p><strong>Note:</strong> I want to know if email has been read so the image src is actually an aspx page having some logic. That's why height width is zero.</p>
