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);
}
