Alt image tags still not displaying

I am running version 3.3.6 with WP version 4.9.5.

I have set ALT values in the media library, and have altered the slide markup to look like this:

<div class="rsContent">
  <img src="{{image_url}}" alt="{{alt}}" class="rsImg" />
  <div class="container">
  <a class="rsLink" href="{{link_url}}">{{title}}</a>

However, the alt values on the rendered HTML are completely blank still for all images. The Alt tag is a required field on all image elements, so this should be right in the core without the need for any modifications.

How can I get alt tags to display?

    Default source of alt attribute for images used by {{image_tag}} is based on a type of slider that you're using.

    • For "custom" type of slider it is based on a title of a slide or its contents, if available.
    • For "[gallery]" it's based on media attachment, and only it supports {{alt}} variable.
    • For "instagram" and "youtube" it's based on photo/video title.

    You can find list of supported variables at

    Then this needs to be changed because it makes no sense to use ‘title’ when
    in Wordpress media library there is a standalone attribute input for alt.

    So surely, you should be using that? Can you adapt your plugin so it can
    natively pull it from the Alt value?

    "custom" type of slider supports many variations of image sources, not just WordPress media library.

    If you want the plugin to use fields from media library - use type of slider that overrides default WordPress [gallery], it supports {{alt}} as well as{{title}}and{{description}}`.
