Provide text-only pages with equivalent information and functionality if compliance with accessibility provisions cannot be accomplished in any other way.

When no other solution is available, one option is to design, develop and maintain a parallel website that does not contain any graphics. The pages in such a website should be readily accessible, and facilitate the use of screen readers and other assistive devices.

As a rule, ensure that text-only pages are updated as frequently and contain all of the same information as their non-text counterparts. Also inform users that text-only pages are exactly equivalent and as current as non-text counterparts.
