In greenshot settings>plugins>imgur plugin>configure>I ticked 'used anonymous access', screenshot: http://i.imgur.com/nQwXz8P.png This allows me to upload to imgur without needing any imgur login.
I use greenshot to 'capture region' and 'upload to imgur'.
Q1) Is the uploaded imgur also saved inside my PC?
Q2) Is the uploaded (uploaded without needing any imgur login) default privacy imgur image 'hidden' or 'public'?
Q3) How to delete the uploaded (uploaded without needing any imgur login) imgur image?
(note: In a logged in imgur account, there is an option to choose default album privacy 'hidden' https://i.imgur.com/ovoR6m7.png or 'public' https://i.imgur.com/nCBsGAb.png , I am not sure what is the default for a non logged in imgur image uploaded)
