A picture may be worth a thousand words but what might those words be? How do we go about finding those words? Images are often used to convey information, supplement textual content, and/or add visual appeal to documents. Unless the user can see the image and properly interpret it, the user may not receive the same information. While containers exist for providing text alternatives in various types of electronic documents (including Web pages), they are rarely used. When they are used, the text alternatives are not informative. While guidance currently exists regarding which containers to use in order to provide text alternatives, there is little guidance available regarding what information to include in these containers and how to compose text alternatives. The purpose of this work is to establish a procedure for identifying the information being communicated within an image and provide guidance on how to produce informative text alternatives.
