Thank you but I tried the PHP extension for imagick and the opening of
my jpeg files didn't work (it did with smaller files).
Does someone know any software that can handle such big files ? Thx.

GD lib needs lots of memory to store the image converted to it's
internal format, which is very memory consumpting.
So GD just don't have enough memory to do it.
Use console tools (ImageMagick for example) to work with such a large
files, this is not a PHP bug.

Description:
------------
I wrote a script that uses GD to slice big jpeg files (about 50mb,
21600x21600) into small 100x100 jpeg.
To make this, I have to open these big files and I use the function
imagecreatefromjpeg.
While loading (HDD is working), I receive this error:
FATAL: emalloc(): Unable to allocate 86400 bytes
I have tested different values of memory_limit in php.ini ( and with
--enable-memory-limit) even the unlimited value of -1: always the same
error.
This error happens only with very big jpeg files (37mb and 47mb), not
with about 4mb jpeg.
Reproduce code:
---------------
Launching PHP in Command Line mode under Windows XP:
php "myscript.php" --enable-debug --enable-memory-limit
The PHP Code is very simple :
$img = imagecreatefromjpeg("bigfile.jpg");
Expected result:
----------------
Opening of the image.
Actual result:
--------------
FATAL: emalloc(): Unable to allocate 86400 bytes
