HELP!! JavaScript Riddle:

[greenhedonist]

I can get an 'onmouseover' img in cell-A to REPLACE a 'ghost' img (a transparent png) in cell-X. --- What I need to do is get 6 separate cells (cell-A-F) to each LOAD a different img in cell-X 'onmouseover' AND REVERT to an empty cell 'onmouseout'.

Our GoogleFu has failed us on the topic... Anybody have an idea or a source?
