The site is working just fine and I used it couple of hours ago. Guess what; I am now using talk image to publish the images on micro tasking site where I am working as part time maker. They require us to post the images on their site as proof of task.
While I understand that you liked so much of the product that you want to spread awareness about it you should already have read on the OP the following entry:
Account ____________________This service is intended for exclusive use on BitcoinTalk, in this sense only forum users can have an account on TalkImg, for this reason the account creation option is not active for the general public. Users who want to have an account should contact
joker_josue by PM to request it. The request will be evaluated and if approved the account will be created.
Load from external sources is an expense on joker_josue end that isn't feasible at all (considering the effort that it takes running the service for the forum alone).
