[Plugin: NextGen-Gallery] HTML5 errors

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/. 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.
