title: jQuery - how to write 'if not equal to' (opposite of ==)
body: <p>I need to reverse of the following code. How can I make the animation run if the width is NOT 500px. </p>
  
  <pre><code>$(".image-div").not(this).each(function() {
          if ($(this).css('width') == '500px') {
              $(this).animate({
                      width: '250px'
                  }, 500, function() {
                  // Animation complete.
              });
          }
  
  
      });
  </code></pre>
  
  <p>In other words, what the opposite of this?: ==</p>
  
  <p>Thanks  </p>
