I wanna use ez_image_alias() function but I dunno what values I have to put in.
Do you have some examples of how to use this function using Twig ?
ez_image_alias
Twig function accepts three parameters:
Starting from your content which is available in a content
variable in your template, you would use ez_image_alias
function like this:
{% set variation = ez_image_alias(
ez_field(content, 'image'),
content.versionInfo,
'large')
%}
variation
variable will now hold an instance of eZ\Publish\SPI\Variation\Values\ImageVariation
object which you can use to render the image:
<img src="{{ asset(variation.uri) }}" />
