Absolutely minimal version of GSIV to work with touch screens and very slow processors.
To view the demo: http://craigfrancis.github.com/zoomify/
This code is not intended to be a final solution that you include in your project, it is intended to create a basic version that you need to read though, understand and customise to your particular needs.
To use as a sub-module:
git submodule add https://github.com/craigfrancis/zoomify.git ./path
You may want to look at:
PanoJS

Works on iPhone, but slow on mobile phones with large images.
GSIV

Where PanoJS came from, but does not support touch events.
Zoomify
http://www.zoomify.com/
Original idea came from, but also has issues (and not open source).
ShiftZoom

Couldn't get the demos to work myself on a mobile phone.
jQuery UI

Fairly basic draggable support (not complete solution - and adds too much).
