Plugin for image pop up on mouse over?

Hi Guys, I am wondering if there is a good plugin to use for this.
I want a little pop up image to appear on mouse over. I don’t want a regular gallery or a window that they have to close after they see it, just an image that goes away again when they move the mouse away.

ie. when they hover over the word “postcard” sample postcard art pops up as a little image.
