将图像放在bootstrap

Question

Bootstrap：如何在另一张图像上设置图像。

  

我使用了jumbotron并在其上设置了图像，然后使用徽标图像？

The big one is a banner image on the jumbotron and over a logo image. I need both is responsive on different sizes on screen.

<div class="jumbotron " style="min-height: 250px">
<div class="container">
    <div class="row">
        <div class="col-md-4 col-xs-4">
            <img class="img-responsive" src="logo1.PNG" />
        </div>
    </div>
</div>
