A jQuery plugin for html zoom/pan (like gmap)

I'd like to pan and zoom arbitrary html in a si开发者_StackOverflow社区milar way that google maps behaves (btw, I see how you can use google maps API with custom images -- not possible with any html content right?)

I see a lot of jquery plugins for panning images, is there any designed for html?

I guess this is what you are looking for:

However, it is not free. Does anybody know a free plugin to achieve a similar pan?

I don't like the answer above because it is not open source. There are many open source ones, the one I ended up using is:
