No redundant image alt

Rule Details

<img> alt prop should not contain image or picture as screen readers already announce the element as an image.

This rule does not discourage conveying the medium of the image which may be considered important to help a user better understand the content. For example, this rule will not flag terms including screenshot, painting, or photograph.
