image_url function in Ruby on Rails

If you need to get the full URL of an image, just put the following code snippet into ApplicationHelper module in your app/helpers/application_helper.rb:

def image_url(source)
  abs_path = image_path(source)
  unless abs_path =~ /^http/
    abs_path = "#{request.protocol}#{request.host_with_port}#{abs_path}"
  end
 abs_path
end

I wonder why this function is not already a standard part of Rails.
