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

#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
