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"|

it should be of course 

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

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)

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.

Did you try with the snapshot?
