Sorry for the lack of a reply. I know imgur hosts only images lol, I'd probably have to use one service for images and another for videos. And yeah it'd have to use some kind of token or authentication and the host would have to allow private content. Guessing that doesn't exist, but just wanted to check.
User images work fine locally, but not externally (online)
Whenever a user uploads an image, I can see it perfectly fine on the server. Once I go online on my laptop, or anything other than the server the image doesn't show up for any user.
Gravatar images are not working reliably either. Some work, some do not. Issues seem sporadic.
I am guessing that you are on the current stable version, 0.9.0?
Yes! latest build
