Routing Error--image routing

Getting the 开发者_StackOverflowfollowing error:

ActionController::RoutingError (No route matches "/public/images/download.png" with {:method=>:get}):

This error means that a request is being made for the following URL:

http://YOURSERVER/public/images/download.png

Typically, this correlates to file in your application's home directory of: public/public/images/download.png

Note the "public" dir nested within the "public" dir
