how to render images to using file_get_contents

hi all,
i asked a question before about making get requests and post requests from a site
and that was the answer :

<?php
$r_default_context = stream_context_get_default
        (
        array
                (
                'http' => array
                        ( // All HTTP requests are passed through a proxy server.
                        'proxy' => 'tcp://192.168.0.222:80', // Make sure IP and port are correct!!!
                        'request_fulluri' => True,
                        ),
                )
        );
 
// Though we said system wide, some extensions need a little coaxing.
libxml_set_streams_context($r_default_context);
?>
<?php
echo file_get_contents(''http://hatem.softwarelab.net');
?>
the code is working perfeclty but have one issue
if there is images with relative pathes it does not appear at all
can any body help me to solve this issue
best regards
HG
