How do I display an image when a user hovers over a link? [closed]

[Sassy2spice]

I have two hyperlinks\[code\]<a href="http://stackoverflow.com/questions/15474855/#">Link 1</a><a href="http://stackoverflow.com/questions/15474855/#">Link 2</a>\[/code\]and two images overlapping each other. Image 1 - has a lower z-index (behind Image 1)Image 2 - has a higher z-index (above Image 1)Image 2 shouldn't show picture until onmouseover of Link 1 or Link 2
