Wow, you're not kidding! I've never used it before but was frustrated by how broken my other choices were and didn't realize how bad that could be. (First choice: imgur. No longer supporting upload from mobile without their app and mandatory sign in. Second choice: DropBox. Their extension is broken and it saved it as a PDF. Then it saved it as a PNG explicitly but the app was making it too hard to get the direct link to the image without using their share sheet and specifying an email address to send to.)

(I am indeed GMT -6, for at least some chunk of the year anyway.)
