* **How to Reference Images in CSS Files from Different Directories in Symfony 2?**

**Option 2 (Highlighting specific issue):**

Path of Assets in CSS Files in Symfony 2

In the context of Symfony 2, there have been difficulties in referencing images in CSS files from different directory structures. Consider the following directory structure:

...
+-src/
| +-MyCompany/
|   +-MyBundle/
|     +-Resources/
|       +-assets/
|         +-css/
|           +-stylesheets...
+-web/
| +-images/
|   +-images...
...

The challenge arises when attempting to reference images in stylesheets while adhering to the best practices of keeping original CSS files in the asset directory (/src/MyCompany/MyBundle/Resources/assets/css/) and images in the public directory (/web/images/).

Initial Solutions

Initial attempts included using absolute paths and Assetic with the "cssrewrite" filter. However, these solutions proved ineffective.

Current Solution

The current solution involves utilizing relative paths in CSS files and adjusting twig accordingly. Instead of using absolute paths, images are referenced as follows:

url("../images/myimage.png")

This solution works in the production environment but encounters an issue in the development environment, resulting in a NotFoundHttpException.

Improved Solution

To overcome this issue, the improved solution involves having the CSS files in a public directory and using the asset function to reference images. Additionally, the original CSS files can be removed after the assetic:dump command. This allows for the desired behavior of keeping original CSS files private while still referencing images correctly.

Final Winner

Upon testing various methods, the best solution emerges as using the asset function with CSS files located in a public directory. This approach adheres to the need to keep original CSS files unpublished while ensuring proper referencing of images.
