<? 
include  ("watermark.php"); 
$iw = new imageWaterMarker(); 
$iw->image_location = 'test.jpg'; <<<<ANYWAY TO CHANGE THIS TO ALL IMAGES IN FOLDER?
$iw->image_type = 'jpeg'; 
$iw->size = 1;  //This could be any value from 1 to 5 
$iw->copyright_text = '(C) 2004 : here'; 
$iw->markImage(); 
?> 

<? 
class imageWaterMarker 
{ 
    var $image_location; 
    var $copyright_text; 
    var $image_type; 
    var $size =1; 

function markImage() 
{ 
    $img = GetImageSize($this->image_location); 
    $width = $img[0]; 
    $height = $img[1]; 
    switch ($this->image_type) 
    { 
        case 'jpg': 
        case 'jpeg': 
        //Here is JPG Loader 
        $im2 = imagecreatefromjpeg($this->image_location); 
        //End JPG loader 
        //Now JPG Text Color Change Tricks 
        $im = imagecreate($width,$height); 
        imagecopy($im,$im2,0,0,0,0,$width,$height); 
        //End Trick 
        break; 

        case 'png': 
        $im = imagecreatefrompng($this->image_location); 
        break; 
    } 
    $black = imagecolorallocate($im,0,32,234); 
    //$black = imagecolorallocate($im,12,132,34); 
    imagestring($im,$this->size,0,$height-30,$this->copyright_text,$black); 
    header ("Content: image/png"); 
    imagepng($im); 

} 
} 
?>

This might do the job:

include  ("watermark.php");
$iw = new imageWaterMarker();
$iw->image_type = 'jpeg';
$iw->size = 1;  //This could be any value from 1 to 5
$iw->copyright_text = '(C) 2004 : here';
$files = glob('*.jpg');
foreach($files as $file)
{
   $iw->image_location = '$file';
   $iw->markImage();
}
