Accessibility issues: Images and the use of ALT Text Screen
reader users, such as the visually impaired, rely upon ALT text for
a textual representation of an image that they may not be able to
see. If the image adds value or meaning to the resource adding ALT
text enables a screen reader user to interact with the resource in
the same way as everyone else An image without ALT text (Screen
reader may announce picture or ignore image without ALT text) Image
with ALT text (Screen reader reads ALT text) Click for slide read
by screen reader JAWS Note: The eLearning Team banner is an image
with ALT text. This gets read out by JAWS. The footer image does
not have ALT text associated with it.

Accessibility issues Appropriate ALT Text In cases where an
image adds no value to a learning resource, and is included merely
for visual effect, good etiquette requires an author to insert
(double parenthesis) in the Alt text field (apart from in
PowerPoint where doing this is counterproductive and the ALT text
field should be left blank). If the ALT text field is left blank
most screen readers will announce picture and the user will be left
wondering whether or not the image was important. On detecting most
screen readers will skip past the item (apart from in PowerPoint
where the screen reader would read double parenthesis...) Advice on
the appropriate use of ALT text can be found at
