How to access avatars from filesystem?

[nirvana43]

Hello,
When avatars are stored in database, they can be accessed by :

http://website.com/forums/image.php?u=userid

But when the avatars are moved to filesystem, how they can be accessed?
Specially when this is required in 3rd party modifications, how it can be achieved?

Cheers!!

Nevermind.. coded my own solution but if someone knows any better way to do this then please let me know.
Below is the custom function i have coded which can return avatars when they are stored in filesystem instead of database :

PHP Code:

//Call below function for every uid
function getUserAvatar($uid = 0)
{
    $adiResult = $vbulletin->db->query_read('SELECT avatarrevision from '.TABLE_PREFIX.'user where userid='.$uid);
    if($row = $vbulletin->db->fetch_array($adiResult ))
    {
        if($row['avatarrevision'] === 0)
            $adiAvatar = 'images/default_avatar_image.jpg';
        else
            $adiAvatar = 'customavatars/thumbs/avatar' . $uid . '_' . $row['avatarrevision'] . '.gif';
    }
    else 
        $adiAvatar = 'images/default_avatar_image.jpg';

        return $adiAvatar;
} 


Cheers!!

Update..
EXIDE has also provided easy solution on this question -

/* Array

        [1] =>  width="80" height="80"

?>

Props to EXIDE.
