Overlay/Watermark Text on Multiple Images with Python

Level: Real-World Project

Project Description

Your task for today is to build a real-world Python script that overlays text on multiple images using OpenCV.

The program should go through all image files in a folder, add a custom text label (like “Sample Text”) to each image, and save the modified images to a new folder.

You can customize the text, font size, color, and position as needed. This kind of tool is useful for watermarking, labeling datasets, or batch-editing photos.

Download these sample images to use them for this project:

Expected Output

When you run the script:

• It should read all images inside a folder called images

• Add the text "Sample Text" to the top-left corner of each image

• Save the edited images in a folder called output
