I did delete those 2 lines, and it still did not do me any good,

first i deleted

PHP Code:

header("Content-disposition:$attachment filename=$attachmentinfo[filename]");
header("Content-Length: ".strlen($attachmentinfo[filedata])); 


then i replaced,

PHP Code:

if ($extension=="gif") {
  header("Content-type: image/gif");
} elseif ($extension=="jpg" or $extension=="jpeg") {
  header("Content-type: image/pjpeg");
} elseif ($extension=="png") {
  header("Content-type: image/png");
} elseif ($extension=="pdf") {
    header("Content-type: application/pdf");
} else {
  header("Content-type: unknown/unknown");
}
echo $attachmentinfo[filedata]; 


with

PHP Code:

$isimage = true;
switch ($extension)
{
    case "gif":
        $header = "image/gif";
        break;
    case "jpg":
    case "jpeg":
        $header = "image/jpeg";
        break;
    case "png":
        $header = "image/png";
        break;
    case "pdf":
        $header = "application/pdf";
        $isimage = false;
        break;
    default:
        $isimage = false;
        $header = "unknown/unknown";
}
header("Content-disposition: inline; filename=" . $attachmentinfo['filename']);
header("Content-type: $header");

if ($isimage)
{
    // watermark options:
    $filename = "watermark.png"; // use a PNG-24 to preserve transparency!

    $im = imagecreatefromstring($attachmentinfo['filedata']);
    imagealphablending($im, true);

    $watermark = imagecreatefrompng($filename);

    $y = imagesy($im) - imagesy($watermark);

    $w = imagesx($watermark);
    $h = imagesy($watermark);

    imagecopy($im, $watermark, 0, $y, 0, 0, $w, $h);

    imagejpeg($im, "", 80);
}
else echo $attachmentinfo['filename']; 


and i still get the red x's for images.
