In Viewer Settings - Mouse buttons - Left double-click - run command
I used to have this set to open the file in GIMP but I've reinstalled windows and cant for the life of me remember how to do it.
I tried this "C:\Program Files\GIMP 2\bin\gimp-2.10.exe %1" but it doesn't work properly.
Can anyone help?
"C:\Program Files\GIMP 2\bin\gimp-2.10.exe" %1
C:\Program Files\GIMP 2\bin\gimp-2.10.exe "%1"
You'll want quotes around the exe path if it contains spaces. (It may work without, by luck, but only until something creates a C:\Program folder and breaks it.)
Whether you also need another pair of quotes around the %1 depends on the program you are running, but you usually do.
