Images detectable

This is an in-progress draft. The content is incomplete and could change substantially.

Core requirement developing

Non-decorative images are detectable.

Applies when content includes non-decorative images.

Procedure

For each non-decorative image:

Check the code to see if it has been marked up in a way that makes it detectable; or
For technologies where the code cannot be checked, use a screen reader to test that the image is detectable.

Expected results

decorative: serving only an aesthetic purpose, providing no information, and having no functionality

Text is only purely decorative if the words can be rearranged or substituted without changing their purpose.

The cover page of a dictionary has random words in very light text in the background.
purely decorative: non-text content that serves only an aesthetic purpose, provides no information, and has no functionality, such that it can be ignored by assistive technology without any loss of meaning or context
