Can't view images

So I logged in recently and found that I'm not able to view any of the pictures on the site at all?

I can see the thumbnails in the search results, but whenever I click on one to view it fully, all I get is a big placeholder box with the little x in the corner. It's the same for every picture I click on.

Is my connection being routed through some weird mirror server that's being blocked by the site's software?

Which browser are you using (and what version)? Are you using a proxy? Are you blocking JavaScript? Do you live in a country that blocks certain websites (e.g Russia)? Are you logging in through a connection that isn't yours (e.g at work or school) and might be blocking the site? Does it still happen when you disable add-ons?
