We could also use a `inject([])` as we don't use `image_set` before/after the iteration.

```ruby
      def images
        object.images.inject([]) do |image_set, image|
          image_hsh = {
            url: add_host_prefix(image.attachment.url(:original)),
            position: image.position,
            title: image.alt,
            type: 'original',
            dimensions: {
              height: image.attachment_height,
              width: image.attachment_width
            }
          }
          image_set << image_hsh
        end
      end
```
