 `react-a11y-img-has-alt`        | Enforce that an `img` element contains the `alt` attribute or `role='presentation'` for a decorative image. All images must have `alt` text to convey their purpose and meaning to **screen reader users**. Besides, the `alt` attribute specifies an alternate text for an image, if the image cannot be displayed. This rule accepts as a parameter a string array for tag names other than img to also check. For example, if you use a custom tag named 'Image' then configure the rule with: `[true, ['Image']]`<br/>References:<br/>[Web Content Accessibility Guidelines 1.0](https://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-text-equivalent)<br/>[ARIA Presentation Role](https://www.w3.org/TR/wai-aria/roles#presentation)<br/>[WCAG Rule 31: If an image has an alt or title attribute, it should not have a presentation role](http://oaa-accessibility.org/wcag20/rule/31/) | 2.0.11
