I can't get the plugin to work, I'm using it here:
And I get this error in my Firebug:
TypeError: tag("a", h) is undefined a.tg = tag('a',h) != '' ? tag('a',h).target:'_self'; galler...ver=1.0 (line 41)
Also I see an issue with multiple galleries. In my case I have jquery tabs enabled and I want a gallery inside each tab but that is causing issues with the ids repeating themselves, I suggest that you fix that, because it may be neccesary to call two galleries in the same page like in my case.
