Create a new PNG image in photoshop with transparency. Leave the background transparent so

it doesn't block the image below it when it's used as a watermark.

Use this code to watermark the images...this assumes they are JPEG. If they are not, simply

change imagecreatefromjpeg to imagecreatefromgif (for gif files) or imagecreatefrompng (for

png files).

<?

$imagedir = "yourdirectorypath";
$watermarklocation = "/home/you/watermark.png";

$dir = opendir($dir);
while(($file = readdir($dir)) !== false) {
if ($file != '.' && $file != '..' && is_dir($file) == false) $files[] =

$file;
}

foreach ($files as $key => $path) {
$img = imagecreatefromjpeg($imagedir . $path);
$wmHandle = imagecreatefrompng($watermarklocation);
imageAlphaBlending($wmHandle, false);
imageSaveAlpha($wmHandle, true);
$wmWidth=imageSX($wmHandle);
$wmHeight=imageSY($wmHandle);

$dest_x = $img - $wmWidth - 1;
$dest_y = $img - $wmHeight - 1;

imagecopy($img, $wmHandle, $dest_x, $dest_y, 0, 0, $wmWidth, $wmHeight);
imagejpeg($img, 90, $imagedir . "water_$path");
}


?>
