I wrote this code and save it in pic1.php

<?php

$path = "http://mysite.com/test.png";
header('content-type: image/png');
header ('Cache-Control: no-cache, no-store, max-age=0, s-maxage=0, must-revalidate');
header ('Cache-Control: post-check=0, pre-check=0', false);
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header ('Pragma: no-cache');
$fgc = file_get_contents ($path);
print $fgc;

?>

and also wrote this code and saved it in pic2.php

<html>
<body>

<h4>title1</h4>
<img src="pic1.php" />
</body>
</html>

but when I open pic2.php by browser, I can not see any image
and when open pic1 I just see a blank page

please somebody help me...whats the wrong?

Can you tell us what the point of doing this is?
Are you trying to display the image without showing the file location?
I think PHP GD might be the better approach.

Assuming the HTTP headers are correct, since you are passing a filename to file_get_contents() have you made sure that fopen wrappers have been enabled? Check the note about that here - http://ca3.php.net/manual/en/function.file-get-contents.php

Using GD:

<?php
$path = "http://mysite.com/test.png";
$img = imagecreatefrompng($path); // open image
// output image to browser
header("Content-type: image/png");
imagePng($img);
// clear memory
imagedestroy($img);
?>

hi thanks for the answe

I removed the empty lines before "<?php" in file pic1.php and it works now!

my actual code (in pic1) is this:

<?php
include("../config.php");
check_log();
global $db;
if(!sizeof($_GET))
{
$t=user_type();
if(class_exists($t))
{
$pic=new $t();
$pic=$pic->custome_find("personal_code",user_name(),1);
$image=base64_decode($pic->get_value('picture'));
if(strlen($image)>100)
print $image;
else
print file_get_contents(dirname(__FILE__)."/def_pic.png");
}
else
print file_get_contents(dirname(__FILE__)."/def_pic.png");
}
else
{
$t=$_GET['type'];
$id=$_GET['id'];
$pic=new $t();
$pic=$pic->custome_find("id",$id,1);
$image=base64_decode($pic->get_value('picture'));
if(strlen($image)>100)
print $image;
else
print file_get_contents(dirname(__FILE__)."/def_pic.png");
}
?>

but for this code didn't work.

for test if I replace this line (line 20)

print file_get_contents(dirname(__FILE__)."/def_pic.png");

with this:

{
$path = 'http://mysite.com/def_pic.png';
header('content-type: image/png');
header ('Cache-Control: no-cache, no-store, max-age=0, s-maxage=0, must-revalidate');
header ('Cache-Control: post-check=0, pre-check=0', false);
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header ('Pragma: no-cache');
$fgc = file_get_contents ($path);
print $fgc;
}

but it didn't work...
( I sure the code in that line works becuase I tested it with a sample code

print "sample text"

)

The reson of second error was "include file!"..becuase I saved it with UTF-8!
