It looks like you are trying to put the image as the background of the navigation which according to your code is to be 330px tall. That is too tall for the navigation area.
I am under the impression that it is essential to have the image in the background
otherwise the menu will be hidden.
I purposely set a DIV background-colour and made the height
100px greater than the background image to illustrate the changes.
Another thing I did not mention is that the image that i am tryign to get to overlay will change from time to time so I would prefer not to make it a code change in css. I really need to kep it as part of the content area.
I do not understand your extra requirements, please supply a link to the page or include the page source.
