Create your own water mark image first. Then merge with your existed photo.

Here is PHP watermark tutorial. A few line code

The faster way, is to use the composite command from linux, with php.

Write the script to watermark one image. Then traverse the directory and apply the watermark to each image.

is there any built-in function to traverse the directory

Yes. Take a look at the directory functions.

i got what i want but i can ONLY view 1 image and i m trying to view all images in the directory but i still cannot

here is part of my code

$i=0;
while (($file = readdir($dh)) != false) {
$i++;
if($i > 2) $file_array[$i]['name'] = $dir.'/'.$file."";

}

$num=2;
while($num < $j){
$num++;

  Draw($file = $file_array[$num]['name']);

}

function Draw($file){
$WaterMark_Transparency = "50";

// Import the images to use...
// the watermark is a gif (transparency without the white.)
$WaterMark = imageCreateFromGIF("water.gif");
$Main_Image = imageCreateFromjpeg($file);

// Get the width and height of each image.
$Main_Image_width = imageSX($Main_Image);
$Main_Image_height = imageSY($Main_Image);
$WaterMark_width = imageSX($WaterMark);
$WaterMark_height = imageSY($WaterMark);

// calculate the position of the WaterMark
$MaterMark_x = ($Main_Image_width - $WaterMark_width);
$MaterMark_y = ($Main_Image_height / 4);

//put the watermark on top of the background image.
imageCopyMerge($Main_Image, $WaterMark, $MaterMark_x, $MaterMark_y, 0, 0, $WaterMark_width, $WaterMark_height, $WaterMark_Transparency);

imagettftext($Main_Image, 10, 60, 25, 110, 0, "Verdana", "HAPPY");
// Let the browser know that it is an image..
header("Content-Type: image/jpeg");

// show the image in png format(sharper image)
Imagejpeg ($Main_Image);
}

I suggest that you copy 3 images into a test directory. First write the function to watermark an image. Your current Draw() function displays the watermarked image - but you want to save it (overwriting the original), not display it.

Once that function is working, then deal with the directory traversal.
