title: imagetoolbar meta tag and IE versions
body: <p>There are quite a few questions here on SO about the following meta tag not being HTML5 compliant and therefore will not <a href="http://validator.w3.org/">validate</a> when using <code>&lt;!DOCTYPE html&gt;</code>:</p>
  
  <pre><code>&lt;meta http-equiv="imagetoolbar" content="no"&gt;
  </code></pre>
  
  <p>I also know this tag is specifically for one purpose alone: hiding the toolbar that appears when you hover your mouse over any image in Internet Explorer.</p>
  
  <p>However, I could not find out in exactly which versions of Explorer this is applicable.  When I Googled it, most results only mention IE6, but these threads/pages were posted back in 2004.  I'm wondering if that's because the feature was dropped in IE7+.</p>
  
  <p>I do not care about IE6, but if this meta tag is applicable to IE7, IE8, IE9, etc. I'll need to decide if I want to find an alternative method.</p>
  
  <p><strong>Exactly which versions of Internet Explorer enable the annoying Image Toolbar feature that is disabled via the meta tag above?</strong></p>
