It's a bug and it's not possible in Opera 12.16 and lower to wrap the corners of the image inside the wrapper div.
It can be solved by giving the parent(wrapper) div relative positioning, appending the image as a background image and positioning it using its top and left coordinates.
If the image is big it should be resized using its background-size property.
Here is the updated jsfiddle link: jsfiddle
<div style="position:relative; overflow:hidden; border-radius:200px; width:200px; height:200px; border:1px solid black; background-image:url(http://www.blogcdn.com/www.autoblog.com/media/2012/06/lamborghini-aventador-f16-fighting-falcon.jpg); background-size:200px 200px;"></div>
