ALT text does not affect how an image is displayed but provides the content in an alternative text-based format.
A screen reader will read this aloud.
The person using the device is given context and meaning about how the image relates to the rest of the page.
If no ALT text is provided, a screen reader will simply say ‘image’ or, depending on the device, may read the file name aloud.
ALT is a text version of the book Oneiric.
