Abstract
Enhancement of hypertext pages containing graphical images is provided by extracting,the ALT tag from the markup language to support selection of the corresponding hypertext link by uttering the ALT tag phrase. We describe how to add a speakable phrase for images without ALT tags. The approach also applies to client image maps that can include ALT tags for individual areas. The steps include parsing to extract possible BASE tags reference and client map (MAP tag),retaining any BASE tag for relative references or, if missing, creating one using the original page reference (,) and for each anchor (A tag) containing a page reference (HREF) but without link text, and using the ALT tag text as the link text (,). In the case of a missing ALT tag, creating unique link text.
