Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions.
Thank you for your interest in PHP.
I looked at your file in detail and found out that it was damaged by
meta info editing. Which programs did you use?
This is nothing to really worry about because meanwhile many programs
have workarounds for programs that damage images in the way done to
your image. Even PHP has some workarounds in that area. Anyway every
additonal workaround makes the code harder to maintain and less robust.

Description:
------------
Try to compute the size of an image. The picture with exif works with
photoshop and with any browser. The picture is available at
'http://www.wuelle.de/20016707_2.jpg'.
I don't know what the problem is - Is this an invalid JPEG file or a
php prblem ?
Reproduce code:
---------------
<?php
$original = "20016707_2.jpg";
echo "exif type : ". exif_imagetype($original) ."\n";
$exif = read_exif_data ($original);
while(list($k,$v)=each($exif))
echo "$k: $v<br>\n";
$result = GetImageSize($original);
print_r($result);
echo "\nready\n";
?>
Expected result:
----------------
Information about the picture.
Actual result:
--------------
Content-type: text/html
X-Powered-By: PHP/4.3.2
exif type : 2
