title: Magento: Cleaning up my themes, removing blank.html
body: <p>I'm justing sorting and optimizing my Magento 1.5.1.0 theme and I'm asking myself, for what purpose this code snippet is and whether I can safely remove it.</p>
  
  <p>Talking about this one:</p>
  
  <pre><code>&lt;!--[if lt IE 7]&gt;
  &lt;script type="text/javascript"&gt;
  //&lt;![CDATA[
  var BLANK_URL = '&lt;?php echo $this-&gt;helper('core/js')-&gt;getJsUrl('blank.html') ?&gt;';
  var BLANK_IMG = '&lt;?php echo $this-&gt;helper('core/js')-&gt;getJsUrl('spacer.gif') ?&gt;';
  //]]&gt;
  &lt;/script&gt;
  &lt;![endif]--&gt;
  </code></pre>
  
  <p>Any advice is appreciated.
  Thanks!</p>
