so i need to run my external resources through a very simple proxy shown below:

```php
<?php
$url = $_GET['rsrc'];
header( "content-type:image/jpeg" );
echo readfile($url);
?>

```

it works for many jpegs.

for example here it is pulling something i grabbed off a google image serarch:

but for some reason, it doesn’t work for some jpegs. here’s another one i grabbed from google:  
[![](http://www.themagicmarble.com/v2/localProxyTest.php?rsrc=http://www.telegraph.co.uk/arts/graphics/2007/05/18/bfdecino400.jpg) ](http://www.themagicmarble.com/v2/localProxyTest.php?rsrc=http://www.telegraph.co.uk/arts/graphics/2007/05/18/bfdecino400.jpg)

it’s not even recognizing the second as an image as an image…

are there different headers for different types of jpegs? do i need to differentiate?

[[EDIT]] with the image that does not load, firefox simply spits back the url i entered, but in IE, there’s an error message:

> \<br /\>

> is it possible that the specific server that houses the image denies the “readfile()” command from external domains? hmmmmmm…

anyone know about this domain?
