Opt your images into responsive behavior (so they never become larger than their parent elements) and add lightweight styles to them—all via classes.

## Responsive images

Images in Bootstrap are made responsive with `.img-fluid`. `max-width: 100%;` and `height: auto;` are applied to the image so that it scales with the parent element.

<div class="bd-example">
  <img data-src="holder.js/100px250" class="img-fluid" alt="Generic responsive image">
</div>

{% highlight html %}
<img src="..." class="img-fluid" alt="Responsive image">
{% endhighlight %}

{% callout warning %}
#### SVG images and IE 9-10

In Internet Explorer 9-10, SVG images with `.img-fluid` are disproportionately sized. To fix this, add `width: 100% \9;` where necessary. This fix improperly sizes other image formats, so Bootstrap doesn't apply it automatically.

## Image thumbnails

In addition to our [border-radius utilities]({{ site.baseurl }}/utilities/borders/), you can use `.img-thumbnail` to give an image a rounded 1px border appearance.

<div class="bd-example bd-example-images">
  <img data-src="holder.js/200x200" class="img-thumbnail" alt="A generic square placeholder image with a white border around it, making it resemble a photograph taken with an old instant camera">
</div>

{% highlight html %}
<img src="..." alt="..." class="img-thumbnail">
{% endhighlight %}

## Aligning images

Align images with the [helper float classes]({{ site.baseurl }}/utilities/responsive-helpers/#responsive-floats) or [text alignment classes]({{ site.baseurl }}/utilities/typography/#text-alignment). `block`-level images can be centered using [the `.mx-auto` margin utility class]({{ site.baseurl }}/utilities/spacing/#horizontal-centering).

<div class="bd-example bd-example-images">
  <img data-src="holder.js/200x200" class="rounded float-left" alt="A generic square placeholder image with rounded corners">
  <img data-src="holder.js/200x200" class="rounded float-right" alt="A generic square placeholder image with rounded corners">
</div>

{% highlight html %}
<img src="..." class="rounded float-left" alt="...">
<img src="..." class="rounded float-right" alt="...">
{% endhighlight %}

<div class="bd-example bd-example-images">
  <img data-src="holder.js/200x200" class="rounded mx-auto d-block" alt="A generic square placeholder image with rounded corners">
</div>

{% highlight html %}
<img src="..." class="rounded mx-auto d-block" alt="...">
{% endhighlight %}

<div class="bd-example bd-example-images">
  <div class="text-center">
    <img data-src="holder.js/200x200" class="rounded" alt="A generic square placeholder image with rounded corners">
  </div>
</div>

{% highlight html %}
<div class="text-center">
  <img src="..." class="rounded" alt="...">
</div>
{% endhighlight %}
