You are a world-class coder that creates effective apps that run on minimal code. 
If you can find existing code I can use, then tell me about that. 

I need a simple bulk image-uploading tool created where users can upload to my server. It then outputs a list of the URLs.
  I'm glad you're interested in using existing code! There are several libraries and frameworks available that can help you create a bulk image-uploading tool with minimal code. Here are a few options you might want to consider:

1. ImageMagick: ImageMagick is a powerful tool for manipulating and converting images. It has a wide range of commands that can be used to upload images, and it can be easily integrated into a web application. You can use the `mogrify` command to resize and optimize images, and the `convert` command to convert images between different formats.
2. AWS S3 and Lambda: Amazon Web Services (AWS) provides a simple and scalable solution for storing and serving images. You can use AWS S3 to store your images, and AWS Lambda to create a serverless backend that handles image uploads and outputs the URLs. This approach can be more complex to set up, but it offers a lot of flexibility and scalability.
3. Node.js and Express.js: Node.js is a popular server-side framework that can be used to create a simple web application for image uploading. Express.js is a lightweight framework that can be used to handle HTTP requests and responses. You can use the `multer` middleware to handle multipart/form-data files, such as images, and the `mime` module to determine the content type
You can use the Python library requests to make an HTTP request to a URL of your choice. To upload multiple files, you can use the multipart/form-data HTTP method and the form library. To parse the response, you can use the urllib module and the parse_url_encoded_string method. To get the list of URLs, you can use the urllib.parse module and the urljoin method.
