How to implement
Assign ALT text that exactly conveys the information contained in the image. ALT
• Be short, succinct and straight-to-the-point
• Contain no more and no less information than that in the image
The HTML to insert ALT text is:
<img src=”filename.jpg” alt=”Information conveyed by image” />
How to test
Accessibility Toolbar > Images > Toggle Image/Alt. Images should be replaced by
ALT text which exactly matches the message conveyed by the image.
Why is this important?
Screen readers can’t understand images; instead they read aloud the ALT text for images.
Additionally users with images disabled with see ALT text in place of images.
