It has always been annoying that the Microsoft HDView tool relies on silverlight and forces users to install a plugin. Not to mention that I started embedding the panoramas in my page and that led to problems … crashes and lack of 360 deg awareness. So I took another look around at free hosting tools, and gigapan and 360cities emerged as two good options. Gigapan is picky in that they reject panoramas that are too small. They REALLY mean giga. 360cities has some restrictions, but not as severe.
For now, I am moving to 360cities. While my panoramas are not good enough for them to include publicly, they will host them so I can show them here.
