I’m in the process of migrating my image galleries from Gallery 1.4.4 to Gallery 2.0.2. Some of the 1.x albums aren’t moving properly, so there will be a slight delay while some of your pictures won’t be available. This includes the “Piper Pictures”, the pictures posted by the members of the Piper chat mailing list. In the mean time, the ones that aren’t available in http://xcski.com/gallery/[whatever] will be at http://xcski.com/g1/[whatever].
Sorry for the inconvenience.
