Title: First thumbnail shouldn't overwrite the original image

I found out that the original image gets overwritten by the first thumbnail since they share the same name so I've added a third key to fix that.

Other changes:
- Replaced the deprecated ActiveSupport::SecureRandom with SecureRandom.
- Appended suffixes to thumbnails' filename instead of generating a new name.
