Hello,

First I have to say that this is merely a bug, but since it's not a feature request either, and trivial to fix, here it the report.

As it is, the posting_gen_topic_icons (functions_posting.php) does implement PHPBB_USE_BOARD_URL_PATH constant and therefore never generate fully qualified url for the icons.

Fix :
Find :

 		foreach ($icons as $id => $data)

		{

			if ($data['display'])

			{

Before add :

 		$root_path = (defined('PHPBB_USE_BOARD_URL_PATH') && PHPBB_USE_BOARD_URL_PATH) ? generate_board_url() . '/' : $phpbb_root_path;

Find :

					'ICON_IMG'		=> $phpbb_root_path . $config['icons_path'] . '/' . $data['img'],

Replace with :

					'ICON_IMG'		=> $root_path . $config['icons_path'] . '/' . $data['img'],

Regards,
