Hidden menu: z-index problem maybe?

Hey, long time no post.

I have just added a slidey image accordion type thing to a site I’m updating but it sits on top of my drop down menus. (‘Services’ and ‘gallery’ have drop downs, click on ‘contact’ to see them working). I’ve had a play with the z-index but had no luck, I may have missed a trick though…

Please remove the ‘X’ from the link.

Thanks in advance for any advice.
