I’ve updated the jQuery Image Annotation Plugin and moved it over to the Google Code site. Hopefully this will simplify the updating process.
The plugin now has a bug fixed that caused an error when loading an image with no previous annotations, and also has been tested with jQuery 1.3.2 (although there are a few CSS quirks that need to be ironed out).
I have a plan to develop the plugin further, adding support for toggling annotations on and off, plus enabling multiple annotated images on the same page.
