Image has no accessible name Accessibility Checkpoint

Description

img elements must have an accessible name.

Help

Add an alt attribute describing the image, which screen readers voice instead of the image. Spacer images and purely decorative images should use alt="" without any global ARIA attributes. Do not use alt text containing only spaces since that’s voiced as an unlabeled image.
