No styles or images in initial Symfony2 installation?

Question

I've been playing with Symfony for a bit but for some reason now, whenever I setup a new project the default styles and images are no longer being loaded. What is going on?

Followed the installation steps precisely as per the instructions. I used the composer.phar method and have set permissions correctly.

Here is a screenshot of my unstyled demo page:

If you followed the instrunctions 1 by 1, your assets are not installed...

you can do this, by a php composer.phar update when you added the mentioned extras to the composer.json

"extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "symfony-assets-install": "symlink"
}

or manually by

php app/console assets:install web
