Make sure you don't have any whitespace after the trailing ?> if there
is one, better still get rid of it.
Also I use readfile($name); ... can't remember why


Here is a bit of code I use for passing PDF files which also handles
caching control you can adapt easily for images.


<?php
$cache_time = false;
$requested_time = false;
$filename = $_REQUEST{'filename'];
if(file_exists($filename)){
  $len = filesize[$filename);
  $mtime = filemtime($filename);
  $cache_time = gmdate('D, d M Y H:i:s', $mtime) . ' GMT';
  header('Last-Modified: '.$cache_time);
  $rt = false;
  if(isset($_SERVER['HTTP_IF_MODIFIED_SINCE'])){
    $rt = $_SERVER['HTTP_IF_MODIFIED_SINCE'];
  }
  if($rt) $requested_time = strtotime($rt);
  if($requested_time && $cache_time){
    if($requested_time == $cache_time){
      Header($_SERVER['SERVER_PROTOCOL'].' 304 Not Modified');
      exit;
    }
  }
  header("Accept-Ranges: bytes");
  header('Cache-Control: no-cache, must-revalidate');
  header("Content-type: application/pdf");
  header("Content-Length: $len");
  readfile($filename);
}
