|media
The |media
filter returns an address relative to the public path of the media manager library. The result is a URL to the media file specified in the filter parameter.
<img src="{{ 'banner.jpg'|media }}" />
If the media manager address is https://cdn.octobercms.com the above example would output the following:
<img src="https://cdn.octobercms.com/banner.jpg" />
