title: Html signatures: how to prevent user editing
body: <p>I have made some <code>.html</code> signatures for one of our clients, and there are two things they want I can't figure out how to achieve.</p>
  
  <p>One of them, the client wants the <strong>text inside the signature to not be editable</strong> by the user, that is to prevent them from accidentally changing something in the signature when sending an e-mail. Is this somehow posible?</p>
  
  <p>The second issue, they said <strong>they can resize the images in the signature using the mouse. I also need to prevent this</strong> so that they cannot accidentally deform the logo or enlarge or diminish it. How can I do it? I tried setting <code>width</code> and <code>height</code> attributes to the images, but that doesn't prevent them form resizing it at will.</p>
  
  <p>Any help or orientation will be really much appreciated.
  Thanks</p>
