Sometimes you'll just need to say more about the image than is possible with ALT text descriptions. 250 characters sounds like a lot until you start describing a complex graph or other important image. Also, there's no way to format your ALT text descriptions: you can't select the font, line breaks, or add any other HTML formatting instructions.
That's why both HTML 4 and XHTML support the LONGDESC attribute. This attribute won't appear as a pop-up tooltip like ALT text does in some browsers. Instead, LONGDESC is an actual link to another Web page that contains the complete text description of the image or non-text page element.
Both ALT and LONGDESC attributes are considered critical components of a page's overall accessibility level. Both are Priority One attributes according to the World Wide Web Consortium (W3C).
