does not autoplay and has NO pause button bottom

I have 2 slideshows embedded on different sites
http://upforsale.co.uk/14-wellingborough-2-bed autoplays and has a pause button bottom right
http://venturacottage.com/splash-theme does not and has NO pause button bottom right

I have put the lightbox module settings side by side and both are exactly the same
Please advise what else could be causing the no auto slideshow issue please
