Writing Image-Map Text Alternatives
Writing Image-Map Text Alternatives records a distinct W3C-supported accessibility writing task while keeping implementation mechanics outside the writing guidance.
For an image map, write an overall alternative that explains the map’s context and a distinct alternative for each hotspot that states its destination or action.
Key details
Important caveats
Scope Boundary
This guide covers text-alternative wording; coordinate geometry, responsive hotspot behavior, and redundant-link implementation are separate technical concerns.
Further guidance
Content
Give the image an overall contextual alternative, then give each interactive hotspot wording that identifies the linked destination, person, place, or action.
Purpose
Users who cannot perceive the map visually need both the context of the whole image and meaningful labels for each selectable region.
