>I could not upload anything to imgur from my phone or tablet

What devices are you using? I upload to imgur from my phone all the time. Just do it from a browser in desktop mode, you don't even have to login.

Presumably like any normal person: I installed their application, logged in (I have an account), and was then stonewalled by the lack of any upload apparatus within the general vicinity.
