def full_filename for_file
  name = super(for_file)
  if version_name
    name
  else
    parts = name.split "."
    "#{parts.shift}-original.#{parts.join('.')}"

#identifier ⇒ Object

version :small_square, if: :create_versions?, from_version: :medium_square do process resize_to_fill: [75, 75] end version :medium_square, if: :create_versions? do process resize_to_fill: [200, 200] end

In case we decide to support the squared versions we have to update all existing images with the following snippet: Card.search(type_id: Card::ImageID) do |card| card.image.cache_stored_file! card.image.recreate_versions! end
