How to get the image_path in production without the asset host?

Hi guys,

I would like to know how to get the image_path in production environment without the asset host (using rails 3.1).

There is the image_path helper that returns the image path with md5 and (if set, and it is set) the asset host, but we have not found a way to get the path without the host.

Does anyone know how to do that?
