title: Disable "save image" in iOS web application
body: <p>I want to disable the "save image" menu in mobile web applications that appears when you hold down a finger on an image. I tried the CSS properties:</p>
  
  <pre><code>-webkit-user-select: none;
  -webkit-touch-callout: none;
  </code></pre>
  
  <p>With "-webkit-user-select" the copy menu is disabled but not the one for saving images. "-webkit-touch-callout" seems not to be working (tried on iPad2).</p>
  
  <p>I also tried this javascript:</p>
  
  <pre><code>$('img').live('touchstart,touchmove,touchend', function() {
    event.preventDefault();
  });
  </code></pre>
  
  <p>But without any effect.</p>
  
  <p>Any suggestions?
  Thanks in advance!</p>
