DB: Validate Image Content

In this module, you will implement image content within the end-to-end application. At the data tier, you will use the BSON::Binary type to store binary data within MongoDB, manipulate image sizes and content using ImageMagick/MiniMagick, implement model validation and content size queries using Mongoid. At the API tier, you will implement content size queries and web caching of write-once, read-many content using a custom HTTP ETag and Cache-Control headers. Within the UI, you will load, manage, edit, and upload new content using AngularJS, ng-file-upload, and ui-cropper modules. You will also implement a re-usable component to vview full size images with embedded information and controls that allow you to cycle through a series of images.
