Add 'error_reporting(E_ALL);' to your script:

PHP Warning:  exif_read_data(82728697.jpg): corrupt EXIF header:
maximum directory nesting level reached in Command line code on line 1

Corrupted image -> no bug in PHP.

Description:
------------
I have a script that parses EXIF data from images, displaying them as a
new image (using GD) that contains the data. Lately (I am not sure when
exactly, but I suspect it was after upgrading to STABLE-CVS due to
fixing of the unserialize() bug I suffered badly from), it seems that
most of the important EXIF data is simply not read (like ExposureTime,
etc). I asked someone to verify that the image indeed has the details,
and it looks that it does. Here's a screenshot from his EXIF read:
http://uploaded.fresh.co.il/2005/02/01/76282133.png

Reproduce code:
---------------
$data=exif_read_data("http://uploaded.fresh.co.il/2005/01/23/82728697.jpg";);
print_r($data);

Expected result:
----------------
See all EXIF data stored on file.

Actual result:
--------------
Only part of the EXIF is retrieved:
Array
(
    [FileName] => 82728697.jpg
    [FileDateTime] => 1106515041
    [FileSize] => 102438

    [MimeType] => image/jpeg
    [SectionsFound] => ANY_TAG, IFD0
    [COMPUTED] => Array

            [Height] => 616
            [Width] => 494
            [IsColor] => 1
            [ByteOrderMotorola] => 0
        )
