title: PHP HTML Mail Not Showing Image on Gmail
body: <p>I am using this code to send an HTML mail by PHP</p>
  
  <pre><code>  $to = $theEmail;
    $subject = 'Renewables Toolbox App Password';
    $headers = "From: BC_ROR_Decision_Support_Tool" . strip_tags($_POST['req-email']) . "\r\n";
    $headers .= "MIME-Version: 1.0\r\n";
    $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
    $message = '&lt;html&gt;&lt;body&gt;';
    $message .= '&lt;img src="http://renewablestoolbox.ca/img/rorlogo.png" alt="BC ROR Decision Support Tool" height="42" width="42"&gt;&lt;h4&gt;Hi, '.$theFName.'&lt;/h4&gt;&lt;p&gt; Your Password is: '.$thePass.'&lt;/body&gt;&lt;/html&gt;';
  mail($to, $subject, $message, $headers);
  </code></pre>
  
  <p>Mail is sending and even the <code>&lt;img alt="BC ROR Decision Support Tool"&gt;</code> tag is showing up in console mark up but there is no graphic showing!</p>
