jQuery: Problems with Hover and Image Map

In the example below, a flower is displayed when you hover over the red bar.

The problem is that if you hover over the flower, the image slides up so you can no longer see the flower.

I only want the image to slide up if you stop hovering over the red bar or flower.

The problem is that you're using the hover event which is actually two different events mouseenter and mouseleave. Because the image is not a child of the anchor tag you actually mouseleave the red bar which causes the image to shrink back down. Instead of using hover bind to the mouseenter only for the red bar to grow the image and bind mouseleave to the wrapper div to shrink it back down.
