How to show "Alternative text" of image fields in a custom content type? I created a custom content type that its name is News and has an image field with news_image machanic name and I added an alternative text to it from administration page,
now I want to print that alternative text when the node content type twig template rendered.
what I want to achieve finally is schematically something like below:

&lt;img src="#" title="#" alt="Alternative text"&gt;



  It seems this problem can be traced back to custom content type only
  because alternative text can be printed without any problem in default content type like article.
you can get "alt" property with node.FIELD_MACHINE_NAME.alt (and for image title as the same ), So your answer is 

&lt;img src="{{ file_url(node.field_news_image.entity.fileuri) }}" alt="{{ node.field_news_image.alt }}" &gt;
