Which attribute must be included in the Img Tag to define an image?

The inclusion of the src and alt attributes in the Img Tag is essential for defining and displaying an image in HTML. The src attribute specifies the source file of the image, indicating where the browser can locate the image file to fetch and render it on the webpage. Without the src attribute, the browser will not be able to display any image, as it won't know what image to retrieve.

The alt attribute serves an important accessibility function by providing alternative text for the image. This text is shown if the image cannot be displayed for some reason, such as a broken link or slow connectivity, and it is also read by screen readers used by visually impaired individuals. This attribute helps ensure that the content of the image is communicated even when it is not visually accessible.

Incorporating both the src and alt attributes is important for functional and accessible web design, which is why they are the required attributes for the Img Tag.
