Can't seem to get rid of this annoying issue. I'm using this plugin:

which seems to work fine but on my implementation the slider doesn't always appear when the website is first loaded. If i click on another page and then click HOME again the slider loads.. but why is it not firing first time, every time? here is the url. appreciation to anyone who can take a look as it is driving me crazy. (it may load successful first time, it seems random? so you may need to try a few times for it to fail)

Or does anyone know of a similar plugin, this one is also a little sluggish i can't seem to fix? basically i want the 3 smaller images clickable which bring it into full view in the main slider.
