Yo, here is a little PHP script to import users avatars from PHPBB forums. Copy it to the root of your punbb.
<?php
include ('config.php');
mysql_connect ($db_host, $db_username, $db_password) or die ('F*cK');
mysql_select_db ($db_name) or die ('f*ck');
$old = '/PATH/TO/PHPBB/images/avatars';
$new = 'img/avatars';
$query = 'SELECT * FROM users;';
$result = mysql_query ($query);
echo '<pre>'
while ($u = mysql_fetch_object ($result)) {
$query = sprintf ('SELECT user_avatar FROM phpbb_users WHERE username=\'%s\';', $u->username);
$res = mysql_query ($query);
$p = mysql_fetch_object ($res);
if ($p->user_avatar != '') {
$n = strrpos ($p->user_avatar, '.');
$name = substr ($p->user_avatar, 0, $n);
$ext = substr ($p->user_avatar, $n);
copy ($old . '/' . $p->user_avatar, $new . '/' . $u->id. $ext);
$query = sprintf ('UPDATE users SET use_avatar=1 WHERE username=\'%s\';', $u->username);
mysql_query ($query);
echo '#!/bin/bash' . "\n";
echo 'cp ' . $old . '/' . $p->user_avatar . ' ' . $new . '/' . $u->id. $ext . "\n";
}
}
echo '</pre>';
?>
