^ G74: Providing a long description in text near the non-text content, with a reference to the location of the long description in the short description, WCAG 2.0 technique. WebAim writes: "[T]he alt attribute (sometimes called the alt tag, though technically this is incorrect) is not the only mechanism for providing the content and function of the image. This information can also be provided in text adjacent to the image or within the page containing the image. ... The term alternative text, as used in this article, refers to the text equivalent for an image, regardless of where that text resides. It does not refer solely to the alt attribute of the image tag.
