e-text image usage

E-Text Images

Descriptive images need text equivalents in order to be accessible. Text equivalents (also called "alt text") are phrases or sentences that describe an image's visual appearance and provide any additional useful information.  Depending on the audience and the author's motivation for using an image, the text equivalents may also describe what the reader is expected to learn from the image, instructions on how to take action (such as clicking an arrow image to navigate through online help), or how the image relates to the adjacent text.
