This is an attempt to add the ability to display image annotations like http://fotonotes.net/
The current version is a prototype, and uses javascript to parse through the HTML for <div class="..."></div> tags. See included example.
The next step would be to have Moin generate <script src=".../jquery.annotate-image.js"></script> in the HTML head.
Then the page could have a static image annotation by using manual <div class="..."></div> structures.
Then the next step would be generating the <div class="..."></div> structures from macro/parser output.
