Clip Amazon S3 with Heroku

Question

has_attached_file :image, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => "/:style/:filename"

I'm not sure what it is :path => "/:style/:filename".

I also want to include a style for this attached image, is that the way :? the style I want is this::styles => { :medium => "275x275>", :thumb => "175x155>" }

Basically, what happens here is what I'm setting up for heroku, and I need to use S3, which seems simple, just not used for this conditional agreement material.

Also, I just signed up for an S3 account ... but herokunotified that it was free or something like that. What is the reason for this?
