Maybe I’m overthinking this. I want something with a drag and drop interface that then gives me a link to paste into discord or a forum to show the image directly, as Imgur does.
I could just use a bare web server but I’d have to scp the images over every time.
Note: Lufi encrypts uploaded files and lets one share a link containing a decryption key. It doesn’t let one expose images for other websites to embed. Thus a good tool but not for OP’s purpose?
