I've put this on my fetch.php
<?php
header('Content-Type: image/gif');
header('Content-Transfer-Encoding: binary');
header('Content-Length: '. filesize('image/'.$_GET['id']));
readfile('image/'.$_GET['id']);
unlink('image/'.$_GET['id']);
?>
I can see the image but can't print it. Am I doing the filesize
correctly?

Subject: Re: base64 encoded images and printing
Hi Bill,
This is what I've used for the last 4 years or so and works in every
browser that I've come across, obviously the data is being called from a
database instead.
<?php
//snippet
$query = "select bin_data, file_type from content_images where
image_id=".$_GET['id'];
$result = mysql_query($query);
$line = mysql_fetch_array($result) ;
$data = $line[0];
$file_type = $line[1];
header("Content-Type: $file_type");
header('Content-Transfer-Encoding: binary');
header('Content-Length: '. strlen($data));
print($data);
?>
<img src="foobar.php?id=12345" />
The important thing here is the headers "Content-Transfer-Encoding" and
"Content-Length", which is why IE6 does not work, as without these the
browser gets all upset that it doesn't know the true size of the image
not the proper encoding of the file, this obviously being an image.
It's good practice to put these headers in anyway.
Hope this helps.
Regards,
Kevin Smith
