Changing Image with Hover

Hello friends,

When the mouse comes on the product picture, the 1st picture will disappear and I want the 2nd picture to appear. How can I do that ? Can you help me ?

To save me from writing it, here's something which may help :)

Thank you for your answer. I did the solution as shown, but it didn't work. Or I'm doing something missing.
Can you help me, I'd appreciate it ? Version 4.30
