关于GSAP和Velocity的Dunno 因为你需要的是一些CSS和一些JS或jQuery,我的意思是你可以在vanilla JS中轻松地重写下面的内容:
var $gal = $("#gallery"), $img = $gal.find("> div"),
n = $img.length, i = 0, t;
$img.eq(i).addClass('on');
(function loop() {
t = setTimeout(function(){
$img.removeClass("on").eq(i++%n).addClass("on");
loop();
}, 3000);
}());

*{margin:0;}
html, body{height:100%;background:#444;}
#gallery{
overflow:hidden;
}
#gallery,
#gallery > div{
position:absolute;
top:0; left:0; bottom:0;right:0;
}
#gallery > div{
background: none 50% / cover;
transform:scale(0.94);
transition:0.8s;
opacity: 0;
}
#gallery > div.on{
transition-delay: 0.1s;
transform:scale(1);
opacity: 1;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="gallery">
<div style="background-image:url(//placehold.it/800x600/daa&text=1)"></div>
<div style="background-image:url(//placehold.it/800x600/dad&text=2)"></div>
<div style="background-image:url(//placehold.it/800x600/ada&text=3)"></div>
</div>
