Most of my panoramas are partial panoramas, but some still cover 360 horizontally. Using voffset i have managed to correct the display of partial panoramas (e.g http://lifeinmegapixels.com/location/forums) but not those which have a 360 degree horizontal field of view, (e.g http://lifeinmegapixels.com/location/stpeters). Setting voffset in the <image> tag for these images simply does nothing...
Edit: seems to be working now, server must not have been updating properly... sorry
