Niels. This looks like a fantastic plug-in and desperately needed by many. There's so much potential for this.
However I've just installed it on a test website, and all I get is a spinning 'waiting' image. See http://www.whitegoldwielder.co.uk/sample-page
I've just added a WordPress gallery, added 3 images and activated the plug-in. 'Use as default gallery' is selected. I'm sure I've checked everything. I tried it with the Twenty Ten theme and still no success. Am I missing something obvious? Why isn't it working?
