Like I said, I just use Discord for image hosting now.
I can upload by just pasting into the client, and it works anywhere Discord works. I can access images from anywhere by using/sharing the direct links.
If I can easily and simply upload and access images, that's all I want out of an image hoster. Everything else is signal noise.
That function always struck me as an oversight rather than a feature, since the rest of the product is oriented around only being available "in the app".
Personally I am running a mediagoblin server on a Droplet but I have a feeling that only works as long as nothing I make ever goes viral.
I frequently use Imgur because of its built in support in various tools such as Greenshot.
