Promote Drupal - Pitch deck: add alternative text to images

Problem/Motivation

The current slide deck does not provide alt text on images.
Drupal Pitch Deck v2.0

When we add alt text to our images, we allow people who cannot access the images visually to have the same experience as those who can see the image. This benefits low-vision folks who are using assistive technology and folks who might have poor internet and images fail to load.

Steps to reproduce

Select the image and inspect it, or use a screen reader.

Proposed resolution

Add alt text.

In an editable version of the slide deck
Select the image, right-click, and one of the options is to add alt text.

NOTE: this deck is in read-only mode - access is limited to those with elevated permissions.
