The storage usage is at 340GB currently, which is a lot and it’s rapidly increasing. I use Backblaze B2 for my storage. Here is my docker compose file: x-logging: &default-logging driver: “json-file” options: max-size: “50m” max-file: “4”

      This blog post talks about the image proxying mode here

      It basically downloads the pictures temporarily. This wouldn’t account for your existing ones. Assuming you are on one of the most recent versions, you should be able to lookup and delete images on the admin UI as well, but image proxying would only apply to new content.
