Using gem aws-sdk for a ror application for uploading images to s3
Uploading images to a fixed bucket with different folders for each object or application.
The s3 keeps a limitation on the number of buckets creattion whereas there is no
limitation for content inside a bucket.

This code will upload image for a user to s3 using aws-sdk gem. The bucket and the image uploaded are made public 
so that the images uploaded are directly accessible. The input it takes is the image complete path 
where it is present, folder in which it should be uploaded and user_id for whom it should 
be uploaded.
