<s>[INST] This is a project and I'm gonna need your help. Specifically, I need help with library suggestions.

I wrote a restful API designed to handle editing image dimensions. It can change the image's height, width, orientation and even add a border to the image.

The library I used to edit the images is Pillow. Now here's where I need your help. The current implementation doesn't allow multiple images to be edited at the same time (per request). If someone sends multiple image requests to the server, the current implementation waits until the previous one is fully processed before starting with the next one. This is the problem.

I'm looking for libraries to help parallelize editing multiple images at the same time. I have looked at both `concurrent.futures` and `'multiprocessing'` libraries. Could you suggest some other libraries or solutions that might be useful for this scenario?[/INST]
