Bootstrap 2.x

您可以创建一个新的CSS类，例如:

You could create a new CSS class such as:

.img-center {margin:0 auto;}

然后将其添加到每个IMG:

And then, add this to each IMG:

 <img src="images/2.png" class="img-responsive img-center">

或者，如果要将所有图像居中，只需覆盖.img-responsive.

OR, just override the .img-responsive if you're going to center all images..

 .img-responsive {margin:0 auto;}

Bootstrap 3.x

EDIT -随着Bootstrap 3.0.1的发布，现在可以使用center-block类，而无需任何其他CSS..

EDIT - With the release of Bootstrap 3.0.1, the center-block class can now be used without any additional CSS..

 <img src="images/2.png" class="img-responsive center-block">

引导程序4

在Bootstrap 4中，mx-auto类(自动x轴边距)可用于使display:block图像居中.但是，img默认为display:inline，因此text-center可以在父级上使用.

In Bootstrap 4, the mx-auto class (auto x-axis margins) can be used to center images that are display:block. However, img is display:inline by default so text-center can be used on the parent.

<div class="container">
    <div class="row">
        <div class="col-12">
            <img class="mx-auto d-block" src="//placehold.it/200">  
        </div>
    </div>
    <div class="row">
        <div class="col-12 text-center">
            <img src="//placehold.it/200">  
        </div>
    </div>
</div>
