1. Pictures which contains information must be described by text



<img src="…" longdesc="The Screenshot of the module shows following functions: on the left ... "

Every picture, which contains valuable information must be described by a special HTML attribute of the element " img" . This attribute is called " longdesc " and is not viewable by standard web browser like Internet Explorer.
















Screen reader programs for blind people use the information in the longdesc attribute to give the user information about the picture.

This example should give a small impression which problems blind or generally physically handicapped people got with unstructured information on websites.
