Learn how to use asset pipeline to add image to a Ruby on Rails application. Images in an application are generally either part of the interface (such as backgrounds, buttons, or icons) or user-provided images (such as product images or photographs). Each type is handled differently. Rails has an image_tag helper method to make adding an image to a template easier. There is also a special stylesheet helper method which is useful for referencing images inside stylesheets.
