HTML img longdesc Attribute
 HTML <img> tag
Definition and Usage
The longdesc attribute specifies the URL of a page that contains a (long)
description of the image.
This attribute is used for browsers that does not support images (like text
only browsers or non-visual browsers).
The alt text of the image is useful for describing images, however, for longer and
more detailed descriptions it is recommended to use the longdesc attribute and a
separate page.
