All you have to do is just copy and paste the code below on to a file name in your localhost.
Take two images any of .JPG OR .PNG OR .GIF
Here for orginal image i have given the name as originalImage.jpg
For water mark image i have given the name as watermark.jpg
So all you have to do is create a PHP file of your desired name then bring two images namely originalImage.jpg and watermark.jpg on to the same directory where the PHP file is created.
Note:-Your GD library must be enabled
DONT EDIT ANYTHING BELOW IF YOU ARE NOT FAMILIAR WITH PHP
