Update where SQL query had a missing right paranthesis.

Good code:

// add thumbnail extension from configuration if missing
if (!defined('THUMBNAIL_IMAGE_FORMAT')) {
tep_db_query(
"insert into ". TABLE_CONFIGURATION ."
(configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, date_added, set_function)
VALUES ('Thumbnail image format', 'THUMBNAIL_IMAGE_FORMAT', 'inherit', 'Set file format of the generated thumbnails. (Default: inherit)', '4', '9', now(), 'tep_cfg_select_option(array('gif', 'jpeg', 'png', 'inherit'), '));"
);
define('THUMBNAIL_IMAGE_FORMAT', 'inherit');
}


FULL PACKAGE!
