 New Comment:

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

I get "Error generating thumbnail".

Yes, I can get the non-working image with my browser and with wget.

Your comment made me think of a config issue, so I tried an original, untouched 
php.ini file with all extensions enabled (not that my own php.ini was really 
tweaked). Still, no go. I do get a couple of warnings for 2 missing libs, but 
they look unrelated to me (one is a spell-checking lib, the other is SQLite3 -- 
neither is documented as a dependency to getimagesize):

PHP Warning:  PHP Startup: Unable to load dynamic library

Description:
------------
The getimagesize function does not work with some (allegedly supported) images. 
I could not observe this on images stored locally, so it only seems to affect 
images retrieved via the http wrapper.

FWIW, URL length doesn't seem to affect this: I tried a shortened URL for the 
image that didn't work, and it still didn't work.

Test script:
---------------
~> php -r '$imgInfo = 
getimagesize("http://upload.wikimedia.org/wikipedia/commons/thumb/d/d9/Disney_Concert_Hall_by_Carol_Highsmith_edit2.jpg/767px-Disney_Concert_Hall_by_Carol_Highsmith_edit2.jpg";);
 print_r($imgInfo);'
~>
~>
~> php -r '$imgInfo = 
getimagesize("https://bugs.php.net/images/logo.gif";);print_r($imgInfo);'
Array
(
    [0] => 130
    [1] => 67
    [2] => 1
    [3] => width="130" height="67"
    [bits] => 8
    [channels] => 3
    [mime] => image/gif
)
~>

Expected result:
----------------
An array of image properties, for both images

Actual result:
--------------
A boolean false on the 1st image, the expected array of image properties on the 
2nd one.
