As you know, the social network VKontakte allows you to hide photos from viewing by not friends. However, there is an error on the site (at least I think so), which allows you to bypass this limitation. This is a new feature for accelerated photo viewing. We go to the page with a photo, which is protected by “privacy settings” and see below the link “Enable accelerated view of photos” ”. Click on it and voila - the hidden photo is displayed.
UPD: according to the latest data on January 2, this bug is disabled. UPD 2: Habrachelovek nekufa found another way to view.
