The url on demo is url for obvious reasons. On my localhost with local
files I get bitten by this bug. One thing to note is that in Windows
when you do NOT add second parameter to getimagesize then it always
works. But I need that second parameter too, so...
Must be something Bill has messed up.
Thanks anyway.

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

Works just fine. Not even 10'000 tries produce any false result. It's
propably just some network thing, as you're accessing the image
remotely. Try it locally. (drop the url)

it should be of course 

Actual result:
--------------
e.g. (in Windows):
try 433: | 0:110 | 1: 73 | 2: 2 | 3: width="110" height="73"|

Description:
------------
Code snippet http://www.exhibitserver.com/getimagesizetest.php works
perfectly on Linux/apache (PHP 4.2.2), but in Windows XP/Apache/PHP
4.3.2 even 1000 times is not always enough to get some data back from
the function. Mostly it needs between 0 and 200 retries before it gets
some data into array.

I have found that this happens and has something to do ONLY with
ImageMagick Mogrify created JPGS (Version: @(#)ImageMagick 5.4.6
06/01/02 Q:8). See aforementioned demo for test image url.



Reproduce code:
---------------
http://www.exhibitserver.com/getimagesizetest.php

Expected result:
----------------
try 0: | 0:110 | 1: 73 | 2: 2 | 3: width="110" height="73"|

Actual result:
--------------
nothing, 

or

try 0: | 0:110 | 1: 73 | 2: 2 | 3: width="110" height="73"|
