Images in Bootstrap are made responsive with `.img-responsive`. `max-width: 100%;` and `height: auto;` are applied to the image so that it scales with the parent element.
In Internet Explorer 9-10, SVG images with `.img-responsive` are disproportionately sized. To fix this, add `width: 100% \9;` where necessary. Bootstrap doesn't apply this automatically as it causes complications to other image formats.

Align images with the [helper float classes](/components/helpers) or [text alignment classes](/components/helpers). A simple centering class can also be used for `block` level images.
