Pinteres hotlinks? They crawl and copy the image. I was talking about "Pinterest/0.1 +http://pinterest.com/"
The image is being loaded inside an iframe. There is no way that an image can force a break from an iframe. If the image is redirected to another image then you'll see the redirected one. If the image is redirected to a html page (my case) then cached image is being shown.
