Finally cracked a slideshow implimentation in Moodle [V8]. It can be viewed running in a block at http://vle.vspreston.lancsngfl.ac.uk/course/view.php?id=1291
For those who want to have a go, I have setup an open access short course on the same site on the following link - http://vle.vspreston.lancsngfl.ac.uk/course/view.php?id=1291
Good luck.
