The “name” attribute is never allowed on the “img” element.

The name attribute on the <img> element is obsolete in HTML5 and must be replaced with the id attribute.

Older pages used <img name="logo"> so scripts could reach the image through document.images["logo"], a pattern common in pre-DOM rollover scripts. HTML5 dropped the attribute. An id serves the same purpose: document.getElementById("logo") finds the image, and document.images also indexes images by their id.

The name attribute is still valid on elements like <input>, <form>, <meta>, and <map>, where it has a distinct function. On <img>, though, it has no valid use in modern HTML.

Invalid example

<img src="logo.png" name="logo" alt="Acme logo">

Valid example

<img src="logo.png" id="logo" alt="Acme logo">

Any script that referenced the image as document.images["logo"] keeps working with the id in place, or can switch to document.getElementById("logo").
