i have just uploaded a new, "official" version of V1.2 to the Download section. It contains some nice new features and some minor bugfixes (see the release notes under Downloads, and the recent threads here in the forum).
i have a new beta version ready that completely works on Joomla 3 (at least here, in my test installation). I tested several templates and resolved some CSS issues - some J3 templates do "strange things" to IMG tags in their CSS.
This will probably also fix some issues reported here with certain J2.5 templates (distorted map and diagram displays etc.).
