Answer 1

You could be having a few problems. However, the first is that you can not write to the file system on Heroku. You will have to implement a different storage mechanism such as s3. You can read about this limitation here: http://devcenter.heroku.com/articles/read-only-filesystem

Answer 2

In your model.

has_attached_file :picture, 
                   :styles => {:large => "275x450>"},
                   :storage => :s3, 
                   :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
                   :path => "appname/:attachment/:style/:id.:extension"

In s3.yml in your config dir:

    development:
      bucket: bucketname
      access_key_id: key
      secret_access_key: key

    production:
      bucket: bucketname
      access_key_id: key
      secret_access_key: key

Then go signup for a bucket at Amazon S3: http://aws.amazon.com/s3/
