I've created a JIRA with an attached implementation of a new client-side image map.
https://issues.apache.org/jira/browse/WICKET-1936 Basically what it does is it borrows some ideas from the VelocityPanel class, in that it generates its own markup. So, it's able to "attach" the AbstractLink objects to <area> elements within the <map>. I think this is a good replacement for ImageMap, since it's not so limiting (works with existing Images and allows any AbstractLink, not just Links). My patch also deprecates ImageMap, so that we can remove it in 1.5 (provided it makes it into 1.4; we could also back port it to 1.3.x).
