Watermark using PHP

How to add watermark on your uploaded image in PHP?

Adding watermark in PHP is very simple. It can be done using PHP image libraries like GD. Using GD functions, we can copy a portion of the image on another image. Check the following code:

function waterMark($source, $dest){
	$mark = imagecreatefrompng('uploads/mark.png');
	$info = getimagesize($source);
	
	if ($info['mime'] == 'image/jpeg') 
    $image = imagecreatefromjpeg($source);

    elseif ($info['mime'] == 'image/gif') 
    $image = imagecreatefromgif($source);

    elseif ($info['mime'] == 'image/png') 
    $image = imagecreatefrompng($source);
	
	$dx = imagesx($image) - imagesx($mark) - 20;
	$dy = imagesy($image) - imagesy($mark) - 20;
	
	imagecopy($image, $mark, $dx, $dy, 0, 0, imagesx($mark), imagesy($mark)); 
	  
	
	if ($info['mime'] == 'image/jpeg') imagejpeg($image, $dest);
	elseif ($info['mime'] == 'image/gif') imagegif($image, $dest);
	elseif ($info['mime'] == 'image/png') imagepng($image, $dest);
}

You can use this function with source and destination image path to add watermark on your source image.

This lines of codes copy the given watermark image onto right bottom of your source image and then render a same sized photo on destination path.
