Accessible Images

An image can be interpreted by the narrative software if you specify an additional description in the "Long Description" field. To make an image accessible fill the Alt Text field.

The value of this box should point to a separate description file. For example, create an HTML file named chartdesc.html and write more detailed information about the image: Amount Spent Chart Description. This chart shows the monthly amount spent on different products…
