Accessibility considerations

Text Alternatives (alt text) are an important factor in digital accessibility as they provide an easy way for non-text content (as per WCAG success criterion) to be perceived through various methods including Assistive Technology. Alt text is informative content which conveys the meaning of non-decorative images, and also provides content when images are slow or fail to load.

This helps users who use:

Screen readers
Braille display
Text-to-speech technology

In order to first apply alt text correctly, we need to determine whether an image conveys any meaning (non-decorative) or whether it is purely for presentation purposes (decorative).

Non-decorative images

Require image descriptions as they convey meaning or add context to the content. In order to write the most appropriate alt text (image description) for an image, keep the following in mind:

Describe the message the image is conveying, not what the image is. For example, for an image of a clock that points to 2pm, appropriate alt text would be: “Analog clock with a white face and black arms pointing to 2pm”. Inappropriate alt text would be: “clock”.
Keep alt text to no more than ~100 characters. This allows for a streamlined experience for screen reader users.
Avoid using “image of…” or “picture of…” assistive technology will add this for you when encountering the image element.

Decorative images

Do not require image descriptions because they are purely presentational and part of the overall design.

Ensure that the decorative images have an EMPTY alt text attribute: alt="".
