Sequence of images in menu animation

I’m making a main menu for my game and in it I want to have some kind of preview of the level. I want it to look something like this:
I got 3 select level buttons in my level select menu.
When I hover my cursor on one of the butons a small image panel should appear with a sequence of 3 screenshots of the level switching between each other by slowly fading in/out.
Any tutorials/tips/links to videos would be appreciated.
