Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
The memory allocation is:
width * height * channels, which in your case would be upwards of
200megs.

Hi,
i've found a bug with handling gd2 images.
The problem is affected with the bundled libgd (2.0.12).
I've convert an image (4932x3543 pixel) with the pngtogd2 tool:
./pngtogd2 mytestpic.png mytestpic.gd2 4932 2
My memory limit is (php.ini):
memory_limit = 162M
The script:
<?php
$filename='mytestpic.gd2';
$image=imagecreatefromgd2($filename);
?>
results an wrong error message:
Fatal error: Allowed memory size of 169869312 bytes exhausted at
(null):0 (tried to allocate 22581552 bytes)
At first, 22581552 bytes is only the filesize of the mytestpic.gd2
file.
Also it shouldn be a problem to load an image with 4932x3543 pixel,
because this image need no more
than 69896304 bytes (3+1 channels).
Regards,
Steve
