Web Content Checkpoints


A. 1 Provide alternative text for all images, applets, and image maps

  1. Provide alternative text for all images (e.g., in HTML, via the "alt" attribute of the IMG and INPUT elements, or via "title" or within the content of OBJECT). Note. This includes images used as image maps, spacers, bullets in lists, graphical buttons and links. [Priority 1]
  2. Provide alternative text for all applets and other programmatic objects (e.g., in HTML, via the "alt" attribute or within the content of APPLET, or via the "title" attribute or within the content of OBJECT). (See also A.11) [Priority 1]
  3. For all image map links, provide alternative text for each link (e.g., via the "alt" attribute of HTML AREA element). [Priority 1]
  4. For all image map links, provide redundant textual links. [Priority 2] if client-side image maps are used, [Priority 1] for server-side.
  5. Do not use an image map to create a set of buttons in a form. Instead, use separate buttons or images (accompanied by alternative text). [Priority 2]
  6. Replace ASCII art with an image and alternative text. [Priority 1] or [Priority 2] depending on the importance of the information (e.g., an important chart). Note. If the description of (important) ASCII art is long, provide a description in addition to alternative text. (See also A.2)
