I know about PixelFed, but I’m not interested in photo sharing social media style. I just want something that works like Imgur when you upload your images as private. Maybe PixelFed has that option?
I hope this is the correct kind of post and the right place to ask, thanks in advance.
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.
