Jquery Slide Box Menu hidden in ie 8

I've built the following site www.marshallareastagecompany.org, and it looks fine in any of the newer browsers, however it seems no matter what i do the navigation gets hidden behind开发者_开发百科 the main image in IE7,8, and i can't seem to fix it.

Any help on this would be great.

Thanks

Well this one's a bit tricky I found one way (at least in developer tools) to fix it and that's to get rid of position:relative on the image and set it's padding-top to 15px rather than using top

So the img would become

<img style="z-index: 1; display: block; padding-top: 15px" class="center" title="MacBeth" alt="MacBeth" src="/public/images/CurrentPlayWide.png"/>
