Avoid "Save As"-Dialog

[BennySHS]

hi guys,

I'm saving files in my database and use this script to download them:

[code]
if(isset($_GET['id']))
{
    $id      = $_GET['id'];
    $query  = "SELECT filename, filetype, filesize, file FROM tbl_bra_wochenangebot WHERE angebotsid = '$id'";
    $result  = mysql_query($query) or die('Error, query failed'.mysql_error());
    list($name, $type, $size, $content) = mysql_fetch_array($result);

    header("Content-Disposition: attachment; filename=$name");
    header("Content-length: $size");
    header("Content-type: $type");
    echo $content;

    exit;
}
[/code]

It works fine, but the problem is that the 'save as'-dialog appears, and exactly this is what I want to avoid. (The file should open in a new browser window)
Anyone can help me out?
Thx a lot,
greets ben
