I couldn't. I guess it could be some cache issues. Try it again. I am sure you won't be able to see those images very soon.
IMO, I think this is ridiculous. We upload image becoz we want to show it to all the people. But imageshack is forcing people to register before they can see their images. WTF. What kind of logic is that? Perhaps they want more people to notice and join their service. But soon, imageshack will become the No.1 lousy image hosting site becoz of this new tactic.
The reason many people do not use attachments here is that they are using the image links for other forums as well as this one. Personally though, I prefer that they use the attachments or at least host their image here.
As far as imageshack goes this is an idiotic new policy. They are just giving their competitors more business. You would think that this is what they wanted in the first place, I do not see what else they could expect.
