Image data from a CORS-enabled image returned from a CORS request can be reused in the element without being marked " tainted". Indicates if the fetching of the image must be done using a CORS request. This attribute is also used when copying and pasting the image to text, or saving a linked image to a bookmark. Visual browsers will also hide the broken image icon if the alt is empty and the image failed to display. Setting this attribute to an empty string ( alt="") indicates that this image is not a key part of the content (it's decoration or a tracking pixel), and that non-visual browsers may omit it from rendering. For these reasons and others, provide a useful value for alt whenever possible. In these cases, the browser may replace the image with the text in the element's alt attribute.
