The latest release of the deep zoom composer allows you to export a collection of images. I have a quick example of selecting a thumbnail (that was found by looping through the metadata.xml file) and having the deep zoom control find that image in its collection and bring that image into view. There seems to be a bug with the y coordinate of the metadata.xml file, as the first row of images always works but anything else and the view is offset on the y axis. Here is my blog post about this in further detail with the example and source code. Any thoughts?
