Using AWS S3 to host images for use in flat file upload?

Hey ya’ll! Does anyone know how to get a hold of the img url’s in bulk from S3? Copy and pasting them one by one just isn’t scalable when I have over 1,000 images.

​

Or if there are any other suggestions on where to host images so that I can do my bulk listing upload flat file…I’m all ears! It boggles my mind that amazon just wouldn’t have a bulk file upload for images that you can use without having to name the files after ASIN…. because it becomes a chicken/egg problem. You can’t bulk upload images without ASINs and you can’t bulk upload listings for ASIN’s without img urls.
