Hey Robert,

Thanks for the update. FYI, Rainer Simon of Yuma-js is working on a plugin for image annotation as well. Perhaps there is room to collaborate. From Rainer:

>>> http://yuma-js.github.com/okfn_plugin.html (for the plugin)
>>> and
>>> http://yuma-js.github.com/yuma2.html (for the standalone library)

As for the specifics of our Json for images, I'll defer to Randall for that answer.
