I don't have admin rights on a PC, but do have Greenshot installed. Having said that, greenshot was installed without any online publishing plugins, but with the
External Command plugins.
So I set out and created a hacky solution with a more or less simple vbs script that uploads images to imgur using the external command plugin.
- download the
.batfile and place them in some folder (has to be in the same folder)
- open Greenshot Settings
- go to the "Plugins" tab
- select "External command Plugin"
- click "Configure"
