I was about to update my thread by replacing the broken imgur images, but found out that all of them have been restored. Seems imgur guys have realized that most of their users are from bitcointalk and reddit. I hope there will be no change again on imgur so it saves my time to update all of the unrestored images for my clients. However I prefer to use talkimg instead, at least for now, to avoid double effort if someday imgur makes another joke in future.
That is a nice move from imgur website and site management. But since we have one of us here as already created image hosting site for the forum, we should encourage him and patronize him to use the site, so that even if in case there is image break out from the site he can fix it very fast since he is with us. Though using imgur and TalkImg is for a personal choice. You can use anyone at the time of using the image.
