Watermarking Images using PHP with Source Code

Seeing one’s work altered without permission can be frustrating as discovering your work on blogs that are void of any credit. The first response for most photographers is to watermark their images, ensuring that their logo or website graces every image that hits the internet.

This Web Application that I am posting is built to create a watermark on an image. The source code that I will share will help you to understand how does watermark in an image is done using PHP. To watermark an image in this web app, first, you must select an image in the given file input in a form. Then, just simply click the "Watermark Image" button to put a watermark in your selected image. The watermark that I have used in this web is an Image with a transparent background, sample watermark images are located inside the "img" folder. The source code itself automatically resizes the watermark image to fit in the image. After the process is being done the finished product will be displayed in the "Watermarked Image" Panel and the image with the watermark is downloadable. If you want a different watermark, you can create your own using Photoshop. This script is coded in PHP 7.1.8 and I don't know if this script will run smoothly on older versions of PHP
