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/
but there is no asset_url to get http://localhost:3000/assets/ceramiques/big/c0d0.jpg
thanks for your feedback
