S3 Media Browser

Can we view all the images in a given S3 Bucket as a list of thumbnails?

# Background / Story

In a client app, we had a report of "missing" images ...
We know that the images are all on S3 but attempting to view them through the AWS S3 console is _useless_ because all it shows is the name+type of file but not the actual image.
So we have have a bucket full of images but no way to view them all in order to determine if the image is in fact in the bucket ... 😞

# Todo

+ [ ] Find an open source script that displays the images in a given S3 Bucket

We had a look at https://github.com/awslabs/aws-js-s3-explorer which looks good,
But it doesn't show the images/thumbnails ...
So we may need to write a lambda function or Elixir program to do this ...

This might be a good starting point:
https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/s3-example-photo-album.html

No repository files or tests are named. Start by reviewing the linked aws-js-s3-explorer project and the AWS JavaScript photo-album example, then define how the proposed app should access a bucket and render its images; done means all bucket images can be viewed as thumbnails.
