hi there!

you could try something like krpano

http://www.krpano.com/

..they provide tools to generate and viewers to handle panoramic images in the browser. they have a html5 & flash version. easy scriptable via xml .

check out this example..html5

really top notch and surprisingly easy to handle. we did some tests earlier this year. generated some panoramic images via modo using a spherical camera. krpano tools took care of the whole conversation process ( cutting into cubical maps, etc...)..there are different plugins to deal with ui and interaction.

..another solution would be something like a js-framework based thing, like
