This is a WhatsApp bot that you can send a photo to to update your website with that photo. The bot receives the message, pulls out the media_url, and uploads it to a GitHub repo into assets/, and adds an <img src="uploaded_image_path"> to the index.html to display the image on the homepage.
It's a Flask app so there are many options for deployment. There aren't really any requirements from the environment. I've chosen Vercel Serverless Python Functions.
Make sure you set the environment variables (see .env.example).
