fix to support external wp-content location

I patched my copy of nextGen gallery to allow it to use a wp-content folder on a different virtual host than the WordPress using it.

First, in wp-config set

define(WP_CONTENT_DIR,'/var/www/wp-conf-dirs/sitename/wp-content');
define ('WP_CONTENT_URL','http://example.com/wp-conf-dirs/sitename/wp-content');
define ('WP_PLUGIN_DIR',WP_CONTENT_DIR.'/plugins');
define ('WP_PLUGIN_URL', WP_CONTENT_URL.'/plugins');

Modify lib/image.php on lines 67-68 replace site_url() with WP_CONTENT_URL

// set urls and paths
                $this->imageURL         = WP_CONTENT_URL . '/' . $this->path . '/' . $this->filename;
                $this->thumbURL         = WP_CONTENT_URL . '/' . $this->path . '/thumbs/thumbs_' . $this->filename;

I also modified nggallery.php to change line 288 to

define(‘WINABSPATH’, str_replace(“\\”, “/”, WP_CONTENT_DIR) );
