To fix this, add `width: 100%;` or `.w-100` where necessary. This fix improperly sizes other image formats, so Bootstrap doesn't apply it automatically. {% endcapture %} {% include callout.html content=callout type="warning" %} ## Image thumbnails In addition to our [border-radius utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/borders/), you can use `.img-thumbnail` to give an image a rounded 1px border appearance.
