PHP exec upsetting get_file_contents

Hi
I'm running with PHP5 on WAMP & have come across a problem. I use the following php script to respond to an <image src="this.php?source=xxx">

Expand|Select|Wrap|Line Numbers

 
 // get $source & $res 

    $command = "convert -geometry $res $source gim29.gif";

    exec($command);

    if (file_exists("gim29.gif")) {

        if($img     = @file_get_contents("gim29.gif")) {

                                  header("Content-type: \"image/gif\"");

                                  print $img;

                                }

                }

This fails - I do not get the image to my browser. Inspecting file gim29.gif shows it to be good - convert did the job. In fact - if I comment out the exec all works well! Also if I substitute the "convert...." with "ls -l" it still fails !!!

More info:
File getim.htm contains:
[CODE}
<html><body>
<image src="./getim.php">
</body></html>
{/CODE]
File getim.php contains:

Expand|Select|Wrap|Line Numbers

 
<?php

    $command="dir";

    exec($command);

    $img=file_get_contents("gim29.gif");

    header("Content-type: \"image/gif\"");

    print $img;

    exit ();

?>

Silly test I know, but demonstartes the problem.
Call getim.htm in browser & PHP/Apache just hangs
Comment out the exec() & all's well

HELP please - I need to use exec() in my scripts
