Attachments are really bbcode tags img and file, so you cannot make difference between local files and remote files.
If you want to block for example file attachments from anonymous users, just change if statement for case 'file' in
components/com_fireboard/sources/interpreter.fireboard.inc.php line 345:
| Code: |
case 'file':
if ($my_id != 0 && $between)
|
Same works for images, too.
If you want only block local files, you need to compare $between with your local url. Something like this should work: if (!preg_match("|mysite.com/images/fbfiles|i", $between)) { tag } else { ask user to log in }. I've not tested this, but..
