[WSG] Could really use some help with image overflow

[Barrie North]

Hi all,   I have a fluid layout and for the life of me can’t get the image to be “cropped” as the screen adjusts.   Here is the link:   http://www.compassdesigns.net/joomlashack/   If you resize the window the image will stay on top. I have played with z-index, overflow:hidden. I can’t for the life of me get this to work.   Anyone fancy jumping in and pointing out the obvious thing I am missing J  ?   Barrie North
