Which attribute in the image tag describes the image?

The attribute that specifically describes the image is the alt attribute. This attribute provides alternative text that conveys the meaning or purpose of the image if it cannot be displayed. This is especially important for accessibility; screen readers use the alt text to inform visually impaired users about the content of the image. Additionally, this text is displayed in place of the image if it fails to load, ensuring that users still have context about what was intended to be shown.

While the src attribute specifies the path to the image file itself, making it essential for displaying the image, the alt attribute takes on the role of describing it. The title attribute can provide additional information about the image but is not a primary description. The width attribute controls the size of the displayed image rather than describing its content. Therefore, the alt attribute stands out as the correct choice for describing the image’s content.
