[Plugin: Portfolio Slideshow] Sometimes slideshow is only partially loading.

HI,

I’m currently having a problem where sometimes when the page is loaded, the slideshows are only partially loading. Refreshing the browser seems to fix the problem, but obviously this is not an ideal situation.

the website in question is: http://www.thelargeglass.co.uk

Any thoughts?
Cheers,
Alex
