title: Symfony 2 - Working with assets
body: <p>I need some tips on how to work with assets in Symfony 2. For example, do we have to always perform the assets:update every time an image is added ? I know Assetic take care of the management on css and javascript files but what about images? What would be the best practice for the front-end development with Symfony 2 ? How do you guys setup your css, images and js files in your app to make it easy to develop, deploy and change ?</p>
