Paperclip Demo

Reference Application

Paperclip Demo Application

Application allows users to manage a list of “friends” using a basic Rails scaffold. Each friend will have a Name and Avatar. Paperclip will provide the image upload and resizing functionality. The app will demonstrate how to create different sized thumbnails, display resized images on different screens, and gracefully degrade to display missing avatars “missing.png” for friends without an avatar.
