Wasserzeichen einfügen

Hallo..

Ich komme irgendwie nicht weiter.

ich würder gerne hier

$inputfile = $upload_dir."/".$_FILES['Filedata']['name'];
$max_width=500 ;
$max_height=500 ;
$outputfile= $upload_dir."b_".$neuerbildname.".jpg";
$quali=90 ;

if (substr(strtolower($inputfile), -3) == 'jpeg' || substr(strtolower($inputfile), -3) == 'jpg')
$srcimg = imagecreatefromjpeg($inputfile);
elseif (substr(strtolower($inputfile), -3) == 'gif')
$srcimg = imagecreatefromgif($inputfile);
elseif (substr(strtolower($inputfile), -3) == 'png')
$srcimg = imagecreatefrompng($inputfile);

if (!$srcimg)
return false;
else {
$img_width = imagesx($srcimg);
$img_height = imagesy($srcimg);

if ($img_width > $max_width && $img_height > $max_height) {
if ($img_height > $img_width) {
$img_height = ceil($img_height*($max_width/$img_width));
$img_width = $max_width;
}
else {
$img_width = ceil($img_width*($max_height/$img_height));
$img_height = $max_height;
}
}
$thumbimg = imagecreatetruecolor($img_width, $img_height);
imagecopyresampled($thumbimg,
$srcimg,0,0,0,0,$img_width,
$img_height,
imagesx ($srcimg),
imagesy($srcimg));

$cutted_w = 0;
$cutted_h = 0;
if ($img_width > $max_width)
$cutted_w = ($img_width-$max_width);
if ($img_height > $max_height)
$cutted_h = ($img_height-$max_height);

$fill_w = 0;
$fill_h = 0;
if ($img_width < $max_width)
$fill_w = ($max_width-$img_width);
if ($img_height < $max_height)
$fill_h = ($max_height-$img_height);

$dstimg = imagecreatetruecolor($max_width, $max_height);
imagefill($dstimg, 0, 0, imagecolorallocate($dstimg, 255, 255, 255));

imagecopyresampled($dstimg, $thumbimg,
$fill_w/2,$fill_h/2,
$cutted_w/2,$cutted_h/2,
$img_width-$cutted_w, $img_height-$cutted_h,
$img_width-$cutted_w, $img_height-$cutted_h);

if (substr(strtolower($inputfile), -3) == 'jpeg' || substr(strtolower($inputfile), -3) == 'jpg') {
if ($outputfile !== false)
imagejpeg($dstimg, $outputfile, $quali);
else
imagejpeg($dstimg);
}
elseif (substr(strtolower($inputfile), -3) == 'gif') {
if ($outputfile !== false)
imagegif($dstimg, $outputfile);
else
imagegif($dstimg);
}
elseif (substr(strtolower($inputfile), -3) == 'png') {
if ($outputfile !== false)
imagepng($dstimg, $outputfile);
else
imagepng($dstimg);
}
imagedestroy ($srcimg);
imagedestroy ($thumbimg);
imagedestroy ($dstimg);
}

noch in das Bild bevor es gespeichert wird ein Wasserzeichen unten rechts ".jpg" einfügen.

Kann man dabei eventuell einer Helfen ?
