It's OK to update the names and descriptions, but same of the uploaded images are duplicates and what's already uploaded elsewhere in the registry, and we want to avoid duplication. I don't see value added by replacing the images in this case.

Applogies, meant to delete the duplicates. I'll add a commit for that
