Why the fuck is this done in flash? There are plenty of decent ways of doing this kind of thing in html5 and there are better technologies that don't have that jarring effect when it switches resolutions as you zoom in.
Why in all these panos is 50% of the image sky? 160 Gigapixels of grey clouds; great.
The zoomed out images are horribly sharpened, makes it look like someone has drawn round the outlines of the buildings in marker pen. When you zoom all the way in and the image switches to the full resolution original it suddenly looks much better (although never in the same place as you were actually zooming to)
The image pans left when you drag the mouse left, sounds sensible when you write it down but this is the wrong way round. When you drag your mouse left the image should move left (pan right)
It's such a shame when all that time and effort put into constructing the thing and the viewing of the image is flawed. Perhaps they should speak to Gigapixel or Microsoft who both have technologies for doing this kind of thing that don't suck.
