It's not just Opera. The URL in that screenshot also gives me a blurry banner in Chromium 33, Firefox 24 and Safari 5.1.

According to https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Img the srcset attribute is only supported by fairly recent versions of most browsers, other than IE where it apparently isn't supported at all.

I tested on latest opera 30.0 and the banner looks fine:

It seems that the issue is arising on old browsers not having support for srcset. See here
http://caniuse.com/#feat=srcset
I'll add a fallback for browsers with no support for srcset.
