How can alt text be misused in web content?

The usage of alt text is critical for providing context and accessibility for users with visual impairments. When alt text is not descriptive enough or left empty for meaningful images, it fails to convey the essential information that the image represents. For instance, if an image is crucial for understanding the content of a page—such as a chart illustrating data points or a photo that adds to the narrative—neglecting to provide clear and specific alt text means that users relying on screen readers will miss out on important contextual information.

Leaving alt text empty or providing vague descriptions diminishes the user experience for those who cannot see the image and disrupts their ability to fully engage with the content. It is crucial to ensure that every meaningful image has alt text that accurately describes its purpose or function within the content to maintain accessibility standards and provide an inclusive experience for all users.
