+  attributes_table do
+    image_row :photo
+  end
+end
+```
+
+<img src="./images/paperclip-image-row.png" height="400" />

+
+<img src="./images/paperclip-image-column.png" height="400" />
+
+> You can pass `style` attribute matching paperclip's style definition
+
+## Shrine
+
+### Image Row
+
+The Shrine implementation receives an optional `image_options` which is then used as the options for the [`image_tag`](https://apidock.com/rails/ActionView/Helpers/AssetTagHelper/image_tag) method.
+```ruby
+show do
+  attributes_table do
+    image_row :photo, image_options: { width: 400 }
+  end
+end
+```
+
+<img src="./images/paperclip-image-row.png" height="400" />
+
+### Image Column
+
+To use the Shrine [derivatives](https://shrinerb.com/docs/plugins/derivatives) you can use the `style` option with the name of the derivative like the example below. In this case you would need to have a derivative created with the `'jpg_small'` name.
+```ruby
+index do
+  image_column :photo, style: :jpg_small
+end
+```
