/**
* An Image is a graphic representation of something.
*
* @accessibility
* If image should be visible to screen readers, textual representation needs to be provided in 'alt' property.
*
* Other considerations:
* - when alt property is empty, then Narrator in scan mode navigates to image and narrates it as empty paragraph.
* - when image has role='presentation' then screen readers navigate to the element in scan/virtual mode. To avoid this, the attribute "aria-hidden='true'" is applied by the default image behavior.
* - when alt property is used in combination with aria-label, arialabbeledby or title, additional screen readers verification is needed as each screen reader handles this combination differently.
