I looked this up first but could not find the solution. My main nav is set to a z-index of 1000. However the juicebox gallery navigation div obstructs the navigation menu - the user can see the menu items but the overly large div area for the Juicebox nav arrows are above my menu items. And the thumbnail will move overtop the main as the page is scrolled down. So, I set my main nav (w-nav) to 9999 but the condition still occurs. What can i do in this instance?

Also is there anyway to control the space between the thumbnails and the main image? I can't seem to make it fixed to about 30px max.

Thanks!
