Load images from CDN

Hi,

I got a project with Sylius and I can’t load my product images from CDN. I set in framework.yml the following line:

framework:
    assets:
        base_urls:
          - 'https://xxxxxxxx.cloudfront.net'

The CSS, JS and some images are loading from this URL, but the product images keep loading from /media/cache. This could be by liipimaginebundle?

Anyone have experienced a similar issue? How did you solve this?

Many thanks!!
