This simple Python util automatically adds an image banner at the bottom of all your images at once.

Either download or clone all of the repository locally and run

$ pip install -r requirements.txt

Otherwise, install opencv-python manually by calling

$ pip install opencv-python

and download the banner.py file.

Put all of your images in the images directory. You can put multiple folders here to keep a hierarchy.
You must put your banner image in the root directory and name it banner.jpg. You can use another format, but you'll have to edit the banner.py file accordingly.

banner.py
banner.jpg
images
├── landscape.png
├── portraits
│   ├── portait1.jpg
│   └── portrait2.png
└── animals
    └── cat.jpg

Then, launch the Python file:

$ python3 banner.py

You will find the pictures with banner added in the imagesProcessed folder.

The banner can have any size and aspect ratio. It will be automatically scaled to match the size of the images.
