Long Description

A course or document may need to use an image which would need a fairly long description to properly describe the content. In this case the recommendation is to include a short summary in the ALT tag which points to or links blind users to a long text description which fully explains the image.

In most cases, the long description should be available to all users. This long description will not only assist blind users but also sighted users who may not understand a complex image.

The examples below will provide examples of long description and how to place them to benefit the most users.

Example Technical Illustration
