Uploading images directly to S3 using Rails / Heroku when they enter the registration form (or something like this)

Scenario

Imagine we are writing a web application with a simple registration page containing something like the following:

• Name
• Email
• Password
• Profile picture

OK, great, then the user clicks "Create Profile". Ideally, we would like the following to happen.

• Our image will be resized on the client (using their processor)

• To send this image directly to S3 to a unique holiday destination. (without going through our hosting server, which cost us dino and precious time on our well-developed single-threaded rail application).

• To find out when our image was successfully uploaded to S3.
