In this lesson, we are going to see the uploader work. We already have the application connected to the S3 API and all of the model components setup. Now we simply need to integrate the HTML elements in the form, and for this we're going to take advantage of the Rails form helper for file uploads.

Now that we know our uploader is working fine, we are going to take the URL sent back to us from the S3 storage engine and render it into an image in the Rails app.

In this lesson, we're going to play a little bit with rendering to learn some new things, including how to work with the image_tag view template helper method provided from Rails through the ActionView module.

Now that we have the ability to upload images and have them render in the application. In this lesson, we are going to learn how to make images clickable.
