Voici le code qui met à jour le sujet `image_upload_id`, il se trouve dans `CookedPostProcessor::update_post_image`

Vous pourriez donc faire un [monkey patch de cette fonction](https://medium.com/@sebastianroyer/prepend-and-super-for-elegant-monkey-patching-24a5b98f4468) et ensuite faire quelque chose comme

```rb
def update_post_image
  super # appel à l'original
  if @post.custom_fields[:your_field_name_upload_id]
    upload_id = @post.custom_fields[:your_field_name_upload_id]
    @post.update_column(:image_upload_id, upload_id) # post
    if @post.is_first_post? # sujet
        @post.topic.update_column(:image_upload_id, upload_id)
    end
  end
end

```
