Ajax slideshow for D7?
The Views Slideshow module relies on the Cycle library, if I'm correct. It supports AJAX / progressive loading in it's current version as seen here:

In my experience, a lot of Drupal modules make the integration of library options unneccessarily complex:
So you could just generate the necessary code via views instead and load the lib yourself via template. Most current slideshow scripts support AJAX loading, so you can choose one that suits you.
