Here's what I'm trying to do: I've got several menu options on my site that I'm using mouse over effects with. If I click on a given menu option a picture shows up and stays there, just as I want it to. But when I click on the next menu option the next pictures comes up like it should, but I need the first one to disappear. How can I do this?

One way here. The large images are stacked on top of each other there, but if spread out, the previous selection should still disappear.
