1525     =================== Images ===========================================
1526
1527     To avoid accessibility problems for people who aren't
1528     able to see the image, you should provide a text
1529     description using the alt and longdesc attributes.
1530     In addition, avoid the use of server-side image maps.
1531     Note that in this DTD there is no name attribute. That
1532     is only available in the transitional and frameset DTD.
