HTML img longdesc Attribute

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.


<img longdesc="URL" />

Syntax Example

<img longdesc="demo_img_longdesc.htm" />

URL The web address of description page. Possible values:
  • An absolute URL - Is used to navigate to another web site (like longdesc="")
  • A relative URL - Is used to navigate within a site (like longdesc="description.htm")
