Users have been having issues with Imgur. The only service that's been relatively problem free is uploading them directly to the site. Using your own private hosting works too if that's something you're into.
Sorry I can't be of more help. It seems every other week between image hosts changing thier ToS and this place having tweaks done behind the scenes it's hard to say what is or isn't going to work.
