I use Snow Leopard as my OS, I haven't been able to see embedded images in MSE for a month.
I deactivated all the extensions (because I looked on the Internet and many people had the same problem because of AdBlock) but still I'm not able to see them. Moreover if I copy the link of the image and paste it to see the image on stack imgur like here (i.stack.imgur.com/btAuw.jpg) the page won't load. Any help is very much appreciated.
