Accessibility Checking for Large Sites
Rocket Validator integrates axe-core version 4.3,
which currently checks 95 accessibility rules, into an automated web site scanner.
Active <area> elements must have alternate text
An image map is a single image with many clickable areas. Like all images, an image map must have alternate text for each of the different clickable areas, as well as for the larger image itself, since screen readers have no way of translating graphics into text.
Screen readers have no way of translating images into words. It is important that all images, including image maps, have
alttext values.Screen readers typically announce the filename of the image if alternative text is missing. Filenames do not adequately describe images and are not helpful to screen reader users.
