In this tutorial, i will give you two examples of how to add a watermark in images using php. The first example we will take png image and add as watermark. The second example we will use jpg image and add as a watermark. we will use imagecreatefrompng(), imagesx(), imagesy(), getimagesize(), imagecopy(), imagepng(), imagedestroy(), imagecreatefromjpeg() and imagejpeg() functions for adding image to watermark.
So, let's see both examples.
Example 1: Using PNG Image
In First example, we will use png image and add watermark on it. You can download dummy images that i used.

$sourceImage = 'demo.png';
$myWatermark = imagecreatefrompng('watermark_image.png');
$watermarkWidth = imagesx($myWatermark);
$watermarkHeight = imagesy($myWatermark);
$image = imagecreatefrompng($sourceImage);
$imageSize = getimagesize($sourceImage);
$wmX = $imageSize[0] - $watermarkWidth - 20;
$wmY = $imageSize[1] - $watermarkHeight - 20;
imagecopy($image, $myWatermark, $wmX, $wmY, 0, 0, $watermarkWidth, $watermarkHeight);
/*
-------- If you want to save image -------
imagepng($image, 'watermark_image_save.png');
*/
imagepng($image);

$watermarkHeight = imagesy($myWatermark);
$image = imagecreatefromjpeg($sourceImage);
$imageSize = getimagesize($sourceImage);
$wmX = $imageSize[0] - $watermarkWidth - 20;
$wmY = $imageSize[1] - $watermarkHeight - 20;
imagecopy($image, $myWatermark, $wmX, $wmY, 0, 0, $watermarkWidth, $watermarkHeight);
/*
