Why do these images load so slowly in Opera?

Question

In FireFox and IE, the images on this page load almost instantly (especially when they're cached by the browser).

But in Opera they load super slow. Even had to select one of them to "reload" to get it to appear. Can anyone see why this would be? Is it a problem with the webpage or how the images are served, or is it a problem with Opera settings? Been looking for image cache settings, but haven't really found anything that looks abnormal...

Answer 1

Here they load about as slowly in Chrome, but the animation seems to appear somewhat slower in Opera. I think the reason they load slowly is that all images redirect somewhere else - for example http://www.triangelos.no/u/10/thumb redirecting to http://www.triangelos.no/uploads/2012/05/4fc4028947b4b_875e059c43d1aaafab4db5afe569f10c.jpg_thumb.jpeg . Browsers are reluctant to cache redirects because they might redirect somewhere else next time, so you'll have to wait while each URL is re-checked before the actual images are loaded from cache.
