BUG? Can not fully show the big size image.

June 03, 2009 06:06AM
Hi all,

I'm new to this community.
I did days of research to setup Nginx + PHP CGI + MySQL for a website. The problem is that client browser can not show the the full image of big size. When I refresh the browser, I can get random results of the image showing. Sometime get partial image showing, sometimes get full image showing. But small images(about 20k bytes) show perfectly.
My platform is Intel quad cores CPU x 1, 4G memory, Intel Gigabyte NIC. CentOS 5.3 with latest updates. OS bundled PHP 5.1.6, Nginx 0.7.59 compiled from source.
The most strange thing is that the same website code works perfectly on another platform. This platform has 1 Celeron CPU(single core), 768M memory and 100M NIC. The software are Fedora 9, PHP 5.2.6, Nginx 0.7.59 compiled from source.
And moreover, same website code works on Apache + PHP + MySQL.
I did a lot of test on the Intel quad cores platform but get no result, such as
Try different web browser IE 6 and firefox 3,
Tried a lot of configuration for nginx.conf, php.ini. Such as increases the buffer size.
Compiled and installed PHP 5.2.9
Compiled and installed kernel 2.6.28.10
...

My test code is

[hr]

<?php
header("Content-type: image/jpeg");
readfile("images/untitled.jpg");
?>

[hr]

This code does [b]not[/b] work.

But html code like below works.

[hr]

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>
<div id="main">
<img src="images/untitled.jpg" width="3000" height="1872" />
</div>
</body>
</html>

I also searched Google for the same problem reported, but got no resolution. My problem seems very rare. Anyone has any ideas?
Thanks in advance!
