How would I show avatars?

[AutomatikStudio]

I'm tying in to vB's user system for a site I'm working on and I'd like to display user avatars throughout the site on lots of non-vb pages. I'm having trouble getting the images to display though.

Here's the query I'm making in my avatar.php file that should display a user avatar:

PHP Code:

$sql = mysql_query("SELECT filedata, dateline, filename
            FROM vb_customavatar
            WHERE userid = '1'");

    $row=mysql_fetch_array($sql);

    header("Content-Length: ".strlen($row[filedata]));
    header('Content-transfer-encoding: binary');
    header("Content-Disposition: inline; filename=\"".$row['filename']."\";");
    header("Content-Type: image/jpeg");
    echo $row['filedata']; 


The query works fine, but it's just plain not showing the image.

Am I missing something?
