See where Shutter keeps its plugins on your computer.
On my computer, it's in
sudo cp utilities/Shutter.pm /usr/share/shutter/resources/system/upload_plugins/upload/Lutim.pm
And restart Shutter if it was running.
Of course, this plugin is configured for the official instance of Lutim (http://lut.im), feel free to edit it for your own instance.

Double-click the plugin in

Someone asks for settings for using Lutim in Sharex. It seems that all the responses are in the API page.
