Use this one if you don't plan to keep adding more and more sigs.

NPC Code:

---

<?php 

  header("content-type: image/gif"); 

  srand((double)microtime()*10000000); 

  $randomtopic = rand(1,5); 

  switch ($randomtopic) {

    2: include("avatar2.gif");

    3: include("avatar3.gif");

    4: include("avatar4.gif");

    5: include("avatar5.gif");

    default: include("avatar1.gif");

  }

?>

Use this one if you'd going to add tons of them. This code removes the need to change the code each time you add more.

NPC Code:

---

<?php 

  header("content-type: image/gif"); 

  srand((double)microtime()*10000000); 

  $i=1;

  $handle=opendir("sigs");

  while ($file = readdir($handle)) {

    if ($file != "." && $file != "..") {

      $dirlist[$i] = $file;

      $i++;

    }

  }

  closedir($handle);

  $randomtopic = rand(1,sizeof($dirlist)); 

  include("sigs/".$dirlist[$randomtopic]);

?>
