Pan and zoom extra large images with DOM or canvas?

Question

Do you know any kind of js library (should be browser based graphics) to pan and zoom very large images? Need to show a huge mosaic with some hover zones with tooltips. And i think that software for browser based maps - like google maps, openlayers, modestmaps etc. can be used for this purposes. But how I should prepare map tiles for this? May be you know a simpler solution? Thanks for attention.

A recent xkcd comic used PanoJS to display a large image.
