Sorry for necrobumping this thread and you may have already found a solution, but you might try Picsur. It's an open-source, self-hosted Imgur clone. The self-hosted aspect might not be exactly what you're looking for, but I did set it up in docker and it worked well and was a simple process.
The development seems to have slowed down a bit, but it does seem feature complete.
I don't understand. What's the point of posting private photos to a federated service? Just use Imgur.

Imgur announced automated image blocking, no NSFW private images, plus purging of non-account images. None of it affected me, but it breaks stuff on the internet.
