Mouse over code for link

Ok I have a link but when you put your mouse over it I want a image to appear.

Anyone have a good code for it?

You could try this

another

No those dont work right.

I want it so that when you hover over a link like

h ttp://mysite.com

I want a image to show up. These sites have it so a image is there first not the link. I already know how to do that.

Thanks
