Informative Image Rules
HTML Markup Details
altattribute should provide a short text equivalent to describe the purpose of the image on the web resource and orient the user to the content contained in the image.
longdescattribute pointing to internal link
longdescattribute of an img element specifies a link to a long description of the image.
- This HTML markup is not well supported in graphical browsers and therefore difficult for authors to test and users to access.
As the result, using
longdescattribute to add text equivalent information beyond the
altattribute is not recommended.
- The best way to use the
longdescattribute is to build an internal link as the content of the attribute. This internal link would direct to the content on the current resource that provides the text equivalent information (longdesc="#linktext").
