It's not an iframe. It's a regular HTML element (
<dt> to be exact) with a CSS property of "
overflow: auto", which creates scrollbars if the content within the element exceeds the element's specified width and/or height. The image (
<img />) is placed within the element. Since the image is taller than the element, and since the "
overflow:auto" property is set, you get scrollbars. That's all for today, class.
P.S. iframes and overflow scrollbars won't work as expected on most tablets and mobile devices.
