What attribute is needed in the <img> tag to specify the image source?

The attribute needed in the tag to specify the image source is "src." This attribute defines the path to the image file that will be displayed on the webpage. By specifying the "src" attribute, you instruct the browser where to find the image, whether it's located on the same server or a different one, by providing a URL or a relative path.

For instance, using tells the browser to look for "image.jpg" in the current directory of the server. It is essential for rendering the image correctly within an HTML document.

Other attributes, such as "href," "link," and "alt," serve different purposes. "href" is typically used in anchor tags for hyperlinks, "link" is not a standard attribute for the tag, and "alt" provides alternative text for the image, which is important for accessibility and SEO but does not define the source of the image itself.
