How to include images for mcelfinder in symfony2?

Question

css

Hello, I have a problem when including css files for elfinder. I do the following, I include all css files in the template:

{% block stylesheets %}
    {{ parent() }}
    {% stylesheets
        '@FMElfinderBundle/Resources/public/css/*'
    %}
    <link rel="stylesheet" href="{{ asset(asset_url) }}" />
    {% endstylesheets %}
{% endblock %}

when elfinder opens, the images are not loaded, the paths to them are written in these css files.
The paths to the images are specified incorrectly, how can I fix this so as not to edit the code of these css.

GET http://site.loc/img/progress.gif 404 (Not Found)

Maybe I'm doing something wrong, please tell me.

Use cssrewrite option

{% stylesheets '@FMElfinderBundle/Resources/public/css/*' filter='cssrewrite' %}
    <link rel="stylesheet" type="text/css" href="{{ asset_url }}" />
{% endstylesheets %}

Or just include styles without assets.
Are the resources on the web installed?
php app/console assets:install --symlink
