Detect Mouseover And Mouseout & Show Coordinates?

This is what my code is supposed to do:

1. create a select list that changes the photo showing, (which I have)
2. create script so that when the user hovers over the image it shows a div
3. when the users mouse is off the image/div shows the coordinates where it last left
4. on mouseout hides the div again (this is the part I'm stuck on)

This is my html:

<style>
#selectdiv
{
position:absolute;
left:10px;
top:10px;
