Alternative Text

Not all users can see the images. Some may be using assistive technology like screen readers or other text-to-speech software which reads the page out loud, and this software will read the alt text instead of the image. There are other situations when the alt text is used too, for instance, if a user has images turned off then they will see the alt text instead of the image. 
 
Adding an image or a graphic to your content without using proper or empty alternative attributes (alt tags), can be extremely frustrating for people with visual impairments navigating your site through assistive technologies.
 
Adding alternative text for images is the first principle of web accessibility. It is also one of the most difficult to properly implement. Alternative text conveys the content and functionality (if present) of an image. It is very rarely a description of what the image looks like. When authoring alternative text, consider what the core information presented by the image is. Asking the question, "If you could not use the image, what text would you use to replace it?" is often a good test to determine appropriate alternative text.
 
When using image alt text, it should not include:
 
“picture of”
“image of”
 
Screen readers automatically announce an image as an image. So an alternative text “Image of an apple” would be read aloud by a screen reader as “image, Image of an apple”.
