Image Maps are essentially just collections of links organized by their relationship to an underlying image. SiteCM supports the creation of client side image maps which can be made compliant with Web Accessibility Guidelines.
The only requirement is to use the alt attribute for both the image and the hot spots.
While SiteCM will not create multimedia, it does allow you to incorporate this sort of content. You should ensure that your media developer is familiar with the WCAG and specify that you need compliant files.
The key requirements for accessibility are subtitles or sign language of the script for videos.
There are additional requirements for interactive multimedia to ensure that people with disabilities can use the material successfully regardless of how they are accessing it.
