Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
The space between ?> and <?php gets sent and consequently
prevents you from sending the header in 2nd php bit.

Description:
------------
While exif_thumbnail function works its practical use seems limited.
Using php 4.3.4 and the latest apache 2.0 build (5/04) the thumbnail of
an image will not be
displayed correctly unless some unknown circumstance exists. For
example: if you use the
script:
<?php
$image = exif_thumbnail('griffon1.jpg');
header("Content-type: image/jpeg");
echo $image;
?>
This will work however, if you use this following script (1 php file):
<?php
// test
?>
<?php
$image = exif_thumbnail('griffon1.jpg');
header("Content-type: image/jpeg");
echo $image;
?>
You will receive this error:
Warning: Cannot modify header information - headers already sent by
(output started at
C:\apache\Apache2\htdocs\index2.php:5) in
C:\apache\Apache2\htdocs\index2.php on line 7
followed by raw image data, not the image itself.
I have also tried using ob_start and ob_flush at the
beginning and ending of the page.. .this will remove the warning, but
you will not see the image, only the raw image data.
Reproduce code:
---------------
<?php
// test
?>
<?php
$image = exif_thumbnail('griffon1.jpg');
header("Content-type: image/jpeg");
echo $image;
?>
Expected result:
----------------
Viewing the thumbnail of an image.
Actual result:
--------------
Raw image data output, no picture.
