How to see user submitted images in Edit Post

This is the scenario I need help with:

1. From the front-end, a user submits a post with multiple image file uploads.
2. I see it’s pending and check it for quality, but the images don’t show in the edit post.
3. I publish and see a picture that’s low quality and I want to remove it.

How can I see the user submitted images when I go in to edit the post? I presume if I know that, I’ll be able to figure out how to delete the picture I don’t want to keep. Thanks for any guidance.
