 * I got two w3c HTML5 validation errors on my site while the nextgen-gallery slideshow
   widget was activated in my 2010 child theme. Below are the errors and the fixes
   I did so that my site is in the green at w3c:
 * 1. Bad value … for attribute src on element img: DOUBLE_WHITESPACE in PATH.
 * …loader.gif ” alt=”” />
 * Syntax of IRI reference:
    Any URL. For example: /hello, #canvas, or [http://example.org/](http://example.org/).
   Spaces should be escaped as %20.
 * Fix: remove space in line 120 of nggfunctions.php.
    old — $out .= “\n”. ‘<img
   src=”‘. NGGALLERY_URLPATH . ‘images/loader.gif ” alt=”” />’; new — $out .= “\
   n”. ‘<img src=”‘. NGGALLERY_URLPATH . ‘images/loader.gif” alt=”” />’;
 * 2. Error Line 128, Column 45: Required attributes missing on element script.
 * <script type=”text/javascript” defer=”defer”>
 * Fix (line 123 of nggfunctions.php:
    old — $out .= “\n”.'<script type=”text/javascript”
   defer=”defer”>’; new — $out .= “\n”.'<script type=”text/javascript”>’;
 * The page with the widget activated loaded as expected in firefox, opera, and 
   IE6 with the changes.
