For those who also post on Reddit (or elsewhere)

[Ofnuts]

I have a plugin to upload the current image as a PNG to imgur, copy the resulting link to the clipboard, and open a page in your browser with it for feedback (this last action can be commented out)

Set up is a bit contrived (you have to obtain an Imgur client id, install a python library, and the script is Linux only) so I won't document it if there are no takers.

So, anyone interested?
