    随机选择，但可能多次选择一张照片 

    var images = [
             "https://s27.postimg.org/a6iaie0tb/image.png",
             "https://s27.postimg.org/euyadkpzz/image.png",
             "https://s27.postimg.org/i37d4d1nj/image.png",
             "https://s27.postimg.org/99ggn9eov/image.png",
             "https://s27.postimg.org/lww7zrtlr/image.png" ];

$(document).ready(function(){
$("#bt").on("click", function(){
	var rand = Math.floor((Math.random() * 5));
	$("#show").attr("src",images[rand]);
})
});
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div><img id="show" src="https://s27.postimg.org/a6iaie0tb/image.png"></div>
<button id="bt">Change images</button>
