edit admin/functions.php, find:

PHP Code:

        if ($avatarurl=="" or ($bbuserinfo[userid]>0 and !($bbuserinfo[showavatars]))) {
            $post[avatar]="";
        } else {
            eval("\$post[avatar] = \"".gettemplate("postbit_avatar")."\";");
        } 


Replace it AS:

PHP Code:

$log_arr_post_userid=$post[userid];
if ($shown_avatar) {$testavatar1=in_array($log_arr_post_userid,$shown_avatar);}
if ($avatarurl=="" or ($forum[forumid]==X AND $testavatar1) or ($bbuserinfo[userid]>0 and !($bbuserinfo[showavatars]))) {
$post[avatar]="";
} else {
eval("\$post[avatar] = \"".gettemplate("postbit_avatar")."\";");
$shown_avatar[]=$post[userid];
unset($testavatar1);
} 


Replace X with your forumid in which you dont want multi-avatars of the same user..

In functions.php find:

PHP Code:

global $bbuserinfo,$session,$ignore,$cookietimeout; 


Replace it as:

PHP Code:

global $bbuserinfo,$session,$ignore,$cookietimeout,$shown_avatar; 


Edit showthread.php, find

PHP Code:

if ($action=="showpost") { 


after that add:

PHP Code:

$shown_avatar=array(); 


That's all..
