I've beem using Imgur for many years, now when they started to give proxy errors I thought that's time to switch to this service. What I can say - everything works as supposed to work. So, goodbye Imgur.
Just one question, maybe I missed something, but what if people not from Bitcointalk will start to use TalkImg? From what I understood from FAQ post, image simply won't be displayed if I will try to post it on Bitcoin.com forum for example?
