Rails - Sep 2011 - Rails 3.1.0 how to pass the full url of an image asset ?

I need to reference the full url of an image stored in the assets,
this url is passed to fancy box to open it

I build the image path in helper  and it get the path
"ceramics/big/c0d0.jpg"  "ceramics/big/c0d2.jpg", ...

but I need to get the full url to these image

asset_path("ceramiques/big/c0d0.jpg")  => 
"/assets/ceramiques/big/
c0d0.jpg"

but there is no asset_url to get 
http://localhost:3000/assets/ceramiques/big/c0d0.jpg
or  http://www.mydomain.com/assets/ceramiques/big/c0d0.jpg

thanks for your feedback

Something like this should do the trick. You can just add this as a helper.

def asset_url(source)
  "#{request.protocol}#{request.host}#{asset_path(source)}"
end
