I am currently working on a fashion marketplace app that enables designers to upload pictures of their clothes and accessories. At this stage, I’m using Django and trying to figure out how to properly implement image uploads without harming the API’s performance. I am also concerned about the use of large images because of the possible repercussions in terms of user experience and costs for storage. Is it wiser to use the likes of Amazon S3 for this purpose or are there better alternatives in optimizing images on Python web frameworks?

I am new to web development and I want to make a contribution to Django based repo where the news website shows dynamically updating nifty Sensex values , Please tell me how to do it without registering to any website , it it possible ?
