I checked the image address (f182a80e96b6d4aa7be83a1a75e4672f.png).It
is located at
E:\vhosts\aofrozencity.net\httpdocs\images\image_system\security_image\images\tmp\).
It is correct.
test.php file is located at
"E:\vhosts\aofrozencity.net\httpdocs\images\image_system\security_image\"
You can check the orginal image file
(http://aofrozencity.net/images/image_system/bugs/f182a80e96b6d4aa7be83a1a75e4672f.png)
and image
(http://aofrozencity.net/images/image_system/bugs/test_php.png
) which is created by php with fwrite/fread.
Between the orginal image file and php image source aren't same.
test.php source here
<?
// Output PNG Image
$file = fopen("images/tmp/f182a80e96b6d4aa7be83a1a75e4672f.png", "r");
$source = fread($file ,
filesize('images/tmp/f182a80e96b6d4aa7be83a1a75e4672f.png'));
fclose($file);
header("Content-Type: image/png");
print($source);
?>
Result:The image
http://aofrozencity.net/images/image_system/security_image/test.php
cannot be displayed, because it contains errors.

Description:
------------
I figured out why the problem is. I found out that fread/fopen doesn't
read image file exactly and properly because I checked orginal image
file code that isn't match the image file code which was from
fread/fopen.
Reproduce code:
---------------
// Output PNG Image
$file = fopen('images/tmp/'.$tmpname, 'rb');
$source = fread($file , filesize('images/tmp/'.$tmpname));
fclose($file);
header("Content-Type: image/png");
print($source);
Expected result:
----------------
"The image cannot be displayed, because it contains errors"
