[Plugin: NextGEN Gallery] Add class attribute when using the_post_thumbnail

I found that when passing array(‘class’ => “my-class”) to the_post_thumbnail doesn’t work as described in Codex when ngg is installed.

Below is a quick hack to make it work for my website. I thought this might help people.

/plugins/nextgen-gallery/lib/post-thumbnail.php
Comment out line 92
	$class .= isset($attr['class']) ? esc_attr($attr['class']) : '';

Add to line 130
	$class .= isset($attr['class']) ? esc_attr($attr['class']) : '';
