facebook friendlist pagnation with foreach?

I'm retrieving facebook friendlist, but it retrieves like a billion photos (exaggerated). I was wondering how can I add pagination within a foreach loop? Also, would my PHP coding be the best way to retrieve the friendslist?

$user_friends = $facebook->api("/me/friends");

     foreach ($user_friends as $friends) {
      foreach ($friends as $friend) {
         // do something with the friend, but you only have id and name
         $id = $friend['id'];
         $name = $friend['name'];
          echo "<img src='https://graph.facebook.com/".$id."/picture' title='".$name."'>";
         echo $name;

      }

Would I need some kind of jquery to do the pagination? Thanks!

You can use the ORDER BY and the LIMIT keywords in an FQL query to make it so you only get a subset of the photos.

Something like (pseudocode)

$lastid = 0;
do 
{
 $photos = fql("SELECT id from photos where id > $lastid ORDER BY id LIMIT 100")
 foreach $photo in $photos
 {
  ... do stuff ...
  $lastid = $photo->id;
 }
} while ($photos.count > 0)

Basically you are limiting your query to 100 photo chunks and keeping track of where you are by ordering the IDs.
