it's admin_shoutbox.png under udmin/buttons/ , but i also added the file in themes/$theme/pics/admin/ but nothing so far...
this code refers to it in admin.php
PHP Code:
if (file_exists("themes/$theme/pics/admin/".$image.".png")) {
$image = "themes/$theme/pics/admin/".$image.".png";
} elseif (file_exists("themes/$theme/pics/admin/".$image.".jpg")) {
$image = "themes/$theme/pics/admin/".$image.".jpg";
} elseif (file_exists("themes/$theme/pics/admin/".$image.".gif")) {
$image = "themes/$theme/pics/admin/".$image.".gif";
} elseif (file_exists("admin/buttons/".$image.".png")) {
$image = "admin/buttons/".$image.".png";
} elseif (file_exists("admin/buttons/".$image.".jpg")) {
$image = "admin/buttons/".$image.".jpg";
} elseif (file_exists("admin/buttons/".$image.".gif")) {
$image = "admin/buttons/".$image.".gif";
}
