vedr. billedbehandling

Jeg er blevet i tvivl om hvordan følgende kode virker :
Jeg kan ikke se hvorhenne/hvordan billedet bliver overført til mappen "lille" ??????????

<?php
// denne del laver thumbnails i 50*50 (thumbnaillille) til thumbnailmappelille

$info = @getimagesize($til);
$percent = 0.5; // if you want to scale down first
$imagethumbsize = 50; // thumbnail size (area cropped in middle of image)
switch ( $info[2] )
{
  case 1:
    // gif
   
// Content type
header('Content-type: image/gif');
$billede1 = tempnam('/var/www/komxx.dk/public_html/lille/', 'f1_');
;
$billede1b = $billede1 . '.' . 'gif';
$billede11 = basename($billede1b);
// Get new dimensions
list($width, $height) = getimagesize($til);
if ($width<100 or $height<100) { 
$new_width = $width ;
$new_height = $height ; }
else {

$new_width = $width * $percent;
$new_height = $height * $percent;  }
// Resample
$image_p = imagecreate($imagethumbsize , $imagethumbsize);  // true color for best quality
$white = imagecolorallocate($image_p, 0xFF, 0xFF, 0xFF); //hvid baggrund
imagefill($image_p, 0, 0, $white);  //hvid baggrund
$image = imagecreatefromgif($til);


// basically take this line and put in your versin the -($new_width/2) + ($imagethumbsize/2) & -($new_height/2) + ($imagethumbsize/2) for
// the 2/3 position in the 3 and 4 place for imagecopyresampled
// -($new_width/2) + ($imagethumbsize/2)
// AND
// -($new_height/2) + ($imagethumbsize/2)
// are the trick
imagecopyresampled($image_p, $image, -($new_width/2) + ($imagethumbsize/2), -($new_height/2) + ($imagethumbsize/2), 0, 0, $new_width , $new_height , $width, $height);
break;

  case 2:
    // jpeg
